The challenge of greening global product chains: meeting both ends
Authors: Vermeulen Walter J. V. , Ras P. J. 
Published: November 2005

AbstractGreening of product chains has come up as an important means to systematically improve the environmental performance of products from cradle to cradle in Europe and elsewhere. Some experience with inter‐firm co‐operation aiming at reducing the environmental impacts has been generated in recent years. Most of these experiences involve cooperation between some of the links in product chains, very often stopping at European borders. Problems of market communication, information availability and information costs prevent companies from going beyond these lines. Also, anonymous markets may prevent communication between producers and end‐users in the West and supplying firms in developing countries. Only very few documented case studies of global greening of product chains are available. Therefore, the challenge here is how to establish interactions with the first links in supply chains. Within the context of South Africa it is of cardinal importance to identify these links to ensure sustainable synergy. European countries are constantly changing the standards of products in order to meet environmental targets. Moreover, European consumer markets are increasingly sensitive to environmentally sound products. From the perspective of South African suppliers there is an increasing need for interaction in their global product chains. In this conceptual analysis we will present the way that should be followed from both ends of the global product chains. Copyright © 2005 John Wiley & Sons, Ltd and ERP Environment.
Leaders, laggards, and the pursuit of foreign knowledge
Authors: Berry Heather 
Published: November 2005

AbstractThis paper analyzes how firms in different technological and market share positions use foreign R&D to augment their technological capabilities. Technology transfer issues and absorptive capacity arguments are examined to analyze the different technological capabilities of leading and lagging firms. In addition, a new strategic rationale (in terms of non‐dominant market share firms) that has not been considered in prior studies analyzing knowledge‐seeking FDI is offered. From a panel dataset which includes information on all foreign R&D investments made by publicly traded Japanese manufacturing firms (from 1974 to 1994), I show that Japanese firms investing in foreign R&D tend to be the non‐dominant market share firms, but also the technologically leading firms across fairly diverse industries. By considering both the technological and market share positions of firms, this study reveals important characteristics that influence when firms use foreign R&D as part of a strategy to augment their technological capabilities.

Authors: Sofina Natalia , Dinnebier Robert , Jansen Martin 
Published: November 2005

AbstractAnhydrous disodium phosphonate, Na2HPO3, was prepared by dehydration of its pentahydrate. The crystal structure of Na2HPO3 was solved from high resolution X‐ray powder diffraction data (P21/n; Z = 4; a = 9.6987(1), b = 6.9795(1), c = 5.0561(1) Å, β = 92.37(1)°; V = 341.97(1) Å3). The crystal structure consists of two types of sodium‐oxygen polyhedra, which are connected via common edges and vertices forming layers perpendicular to [100]. These Na(1)‐ and Na(2)‐layers are interlinked via common edges, forming in a 3D‐framework. The resulting topology is providing oxygen arrangements that please the coordinative requirement of phosphorus(III).

Published: November 2005

AbstractA three‐dimensional polymeric NiII complex, [Ni(bpp)(NIP)(H2O)]n (bpp = 1,3‐di(4‐pyridyl)propane and NIP = 5‐nitroisophthalate), has been synthesized and characterized. The coordination number of the nickel atom is six (NiN2O4) and the coordination environment around the NiII atom may be described as a distorted octahedron in which two nitrogen atoms of “bpp” ligand occupy the cis positions. The effective magnetic moment for this complex indicate that the interactions between two NiII atoms through the effective exchange media are antiferromagnetic. Self‐assembly of these compounds in the solid state via π–π‐stacking interactions is discussed.

AbstractThe two complexes (pydaH)2[Ce(pydc)2(H2O)2]2 · 2H2O (1) and (phenH)2[Bi(pydc)2(H2O)]2 · 5H2O (2) were prepared from the proton transfer compounds containing the 2,6‐pyridinedicarboxylate ion. 1 was synthesized from the reaction of Ce(NO)3 · 6H2O with the proton transfer compound, (pydaH2)(pydc), (pyda=2,6‐diaminopyridine, pydcH2=2,6‐pyridinedicarboxylic acid). 2 was synthesized from the reaction of proton transfer compound, (phenH)2(pydc), (phen=1,10‐phenanthroline), with Bi(NO3)3 · 5H2O. The characterization was carried out using IR, 1H and 13C NMR spectroscopy, elemental analysis and single crystal X‐ray diffraction. The complex 1 crystallizes in the space group $P{\bar 1}$ of the triclinic system, and contains two molecules per unit cell. The structure has been refined to a final value for the crystallographic R factor of 0.0342 based on 8851 reflections. The unit cell parameters are: a = 9.753(2) Å, b = 10.503(2) Å, c = 10.774(2) Å, α = 83.905(4)°, β = 88.089(4)°, and γ = 82.636(3)°. The crystal structure illustrates that cerium atoms are connected together through the four‐membered ring Ce2O2. 2,6‐Pyridinedicarboxylate fragment acts as a tridentate ligand. The molecular structure contains four (pydc)2− ligands, two of which are bridge ligands linking the two central atoms. The complex 2 crystallizes in the space group $P{\bar 1}$ of the triclinic system and contains two molecules per unit cell. The unit cell dimensions are: a = 8.8860(4) Å, b = 12.0132(6) Å, c = 13.0766(6) Å, α = 100.967(1)°, β = 96.681(1)° and γ = 94.191(1)°. The structure has been refined to a final value for the crystallographic R factor of 0.0471 based on 9576 reflections. In this complex, 2,6‐pyridinedicarboxylate moiety has acted as a tridentate ligand and the lattice is composed of binuclear unit, [Bi(pydc)2(H2O)]22−, (phenH)+ counter ions and five lattice waters. In both complexes hydrogen bonds, π‐π stacking and ion‐pairing play important roles in stabilizing the corresponding lattice. The stoichiometry and stability of the ZnII, CdII, PbII, and CeIII complexes with (pydaH2)(pydc) in aqueous solution were investigated by potentiometric pH titration. The solution studies revealed that the stoichiometry of the crystalline complexes of the proton transfer system (pydaH2)(pydc) with CeIII, obtained in this study, and those with ZnII, CdII and PbII, reported in our previous studies, are in close agreements. The complexation reactions of phen, pydc, and 2phen+pydc with BiIII in aqueous solution were investigated by potentiometric pH titrations, and the equilibrium constants for all major complexes formed are described.

AbstractThe methods of preparation of ReO3F are revised. ReO3F is an amorphous yellow solid that crystallizes into colorless needles after prolonged heating. Its structure is that of a fluorine and oxygen bridged chain with hexa coordinated rhenium atoms (a = 670.9(2), b = 596.6(2), c = 1030.6(4) pm, β = 90.057(7)°, space group P2/c. In presence of donor solvents ReO3F·2L (L = (C2H5)2O, (CH3)2O, THF) are formed. ReO2F3, if crystallized from HF, exists in two crystalline forms, both are fluorine bridged chain polymers. (ReO2F3‐I: a = 1539.7(3), b = 999.6(3), c = 924.4(2) pm, β = 95.25(1)°, space group P21/c; ReO2F3‐II: a = 544.9(1), b = 494.2(1), c = 1253.7(2) pm, β = 98.543(7)°, space group P21/c. ReO2F3 crystallizes from CFCl3 or SO2FCl as fluorine bridged cyclic trimer (a = 881.4(4), c = 822.1(6) pm, γ = 120°, space group P63/m, or fluorine bridged cyclic tetramer (a = 1107.8(2), b = 999.4(2), c = 1347.9(3) pm, space group Cmca).
Synthesis and Modulated Crystal Structure of KBaNbS4
Authors: Wu Yuandong , Doert Thomas , Bensch Wolfgang 
Published: November 2005

AbstractSingle crystals of KBaNbS4 have been prepared by the reaction of Nb with an in situ formed melt of K2S3, BaS, and S at 500 °C. Satellite reflections observed in X‐ray diffraction experiments of these crystals indicate the presence of a one‐dimensional lattice distortion. The modulated structure has been solved and refined from X‐ray data using the superspace group approach. KBaNbS4 can be described in the (3 + 1)‐dimensional superspace group Pnma(α00)0s0 with lattice parameters a = 9.187(1), b = 7.001(1), and c = 12.494(1) Å and a modulation vector q = (0, 0.629(1), 0). In the structure the NbS4 tetrahedra are stacked along the a axis and show a slight tilting against each other. The K+ and Ba2+ ions follow this tilting, both are slightly shifted from their positions in the average structure. The modulation does not lead to a significant change in the coordination spheres of the metal atoms. The small effects of the modulation correspond to the relatively weak intensities of the satellite reflections. Results of temperature dependent X‐ray investigations indicate that K+ librates at higher temperatures and the surrounding S2− anions follow this motion. With decreasing temperature the libration of K+ is reduced and the coordination geometry freezes under formation of an incommensurate modulation. The heavier Ba and Nb atoms are also affected by positional modulation of the substructure and accommodate to their environment.
Ag5Te2Cl1−xBrx (x = 0 – 0.65) and Ag5Te2−ySyCl (y = 0 – 0.3): Variation of Physical Properties in Silver(I) Chalcogenide Halides
Authors: Nilges Tom , Lange Stefan 
Published: November 2005

AbstractThe structures, thermal and physical properties of ion conducting polymorphic Ag5Te2Cl1−xBrx and Ag5Te2−ySyCl have been investigated. A maximum substitution degree of x = 0.65 and y = 0.3 was derived from X‐ray powder diffraction. Mixtures of silver halides, silver chalcogenides and Ag3TeBr were observed for higher substitution degrees. Both silver chalcogenide halide systems show a Vegard type behaviour. Single crystal structure determinations of selected materials were performed at different temperatures to analyse the silver distribution in the tetragonal high temperature α‐ and the monoclinic room temperature β‐phases. After non‐harmonic refinement of the silver positions detailed joint probability density function analysis (jpdf) and determination of one particle potentials (opp) were carried out to investigate the diffusion pathways and bottlenecks of ion transport for those materials. A preferred anisotropic ion transport along the $^{1}_{\infty}\rm [AG]$ diffusion pathways for the α‐ and 1D zig‐zag diffusion pathways for the β‐phases were found. α–β and β‐γ phase transitions were determined by DSC and DTA methods and conductivities were measured using temperature dependent impedance spectroscopy. The substitution of tellurium by sulphur lowered the α–β phase transition from 334 K (Ag5Te2Cl) to 270 K (Ag5Te1.8S0.2Cl) while the opposite trend was found for the Ag5Te2Cl1−xBrx phases. The α–β phase transition of Ag5Te2Cl0.35Br0.65 at 343 K represents the highest transition observed for the silver chalcogenide halides under discussion. Total conductivities of approx. 1 Ω−1 cm−1 (α‐Ag5Te2Cl0.5Br0.5) and 0.24 Ω−1 cm−1 (α‐Ag5Te1.8S0.2Cl) at 473 K were found being slightly higher (Br) and lower (S) than the conductivity observed for α‐Ag5Te2Cl. A conductivity jump of more than two orders of magnitude, related to the α–β phase transitions, within the temperature range from 270 to 343 K is adjustable by simple variation of the composition and is therefore an extraordinary feature of these materials. The total conductivity is linearly correlated to the volume of the anion substructure and can be varied within more than half an order of magnitude.

AbstractA new layered zinc phosphite with the formula (NH4)[{Zn(H2O)4}0.5Zn2(HPO3)3] has been synthesized under hydrothermal conditions. Its structure was determined by single‐crystal X‐ray diffraction. The compound crystallizes in the triclinic system, space group $P{\bar 1}$ (No. 2), a = 7.2507(4), b = 9.7982(6), c = 10.2642(6) Å, α = 63.425(2), β = 87.165(2), γ = 72.999(3)°, V = 620.84(6) Å3, Z = 2. The connectivity of ZnO4 tetrahedra, HPO3 pseudo pyramids and ZnO2(H2O)4 octahedra results in macroanionic layers with 4.8 net.

AbstractThe binary intermetallic compound NiMg2 (own structure type) forms a pronounced solid solution NiMg2−xSnx. The structure of NiMg1.85(1)Sn0.15(1) was refined on the basis of single crystal X‐ray data: P6422, a = 520.16(7), c = 1326.9(1) pm, wR2 = 0.0693, 464 F2 values, and 20 variables. With increasing magnesium/tin substitution, the structure type changes. Crystals with x = 0.22 and 0.40 adopt the orthorhombic CuMg2 type: Fddd, a = 911.0(2), b = 514.6(1), c = 1777.0(4) pm, wR2 = 0.0427, 394 F2 values for NiMg1.78(1)Sn0.22(1), and a = 909.4(1), b = 512.9(1), c = 1775.6(1) pm, wR2 = 0.0445, 307 F2 values for NiMg1.60(1)Sn0.40(1) with 19 variables per refinement. The nickel atoms build up almost linear chains with Ni–Ni distances between 260 and 263 pm in both modifications where each nickel atom has coordination number 10 with two nickel and eight Mg/Sn neighbors. Both magnesium sites in the NiMg2 and CuMg2 type structures show Mg/Sn mixing. The Ni polyhedra are condensed leading to dense layers which show a different stacking sequence in both structure types. The crystal chemical peculiarities of these intermetallics are briefly discussed.

Ce29Al14I28: Ein Komposit aus intermetallischer Phase und Metallclustern

Published: November 2005

AbstractCe29Al14I28: A Composite of Intermetallic Phase and Metal ClustersSingle crystals of Ce29Al14I28 form at 900 °C from CeI3, Ce and Al. The compound crystallises in C2/m with a = 19.471(3), b = 4.308(1), c = 19.526(3) Å und β = 102.75(2)°. Pronounced diffuse scattering occurs and is discussed in terms of special disordered arrangements of discrete building units. The structure of Ce29Al14I28 is composed of two characteristic substructures. One part of the Ce atoms forms pairs of face‐linked trigonal prisms which are connected into layers via edges. Al atoms in the prism centers are arranged in ribbons of planar Al6 rings as in the structure of Ce3Al2I2. Between these ordered layers another kind of layers of close‐packed I atoms occur whose octahedral voids are partially occupied by Ce atoms. Some of the I‐atoms are substituted by Al which are completely surrounded by Ce atoms resulting in octahedral Ce6Al clusters. Most of these clusters are connected into Ce10Al2 units via edge‐sharing, and such units are rather ordered within one layer, however, with no long range order and no correlation with adjacent layers. The prism layers represent sections of an intermetallic phase which are separated by non‐metallic cluster structures.
