Abstract
The reaction of SbI3 with Me4NI, Me3SI. and Me3NCH2PhI in acetonitrile (molar ratios 2:1) yields (Me4N)4Sb8I28 (I), (Me3S)4Sb8I28 (2), and (Me3NCH2Ph)Sb2I7 (3), respectively. The struc­tures of 1-3 were determined from single crystal X-ray diffraction data. 1-3 crystallize in the monoclinic space group P21/n. 2: a = 1434.2(3). b = 1484.1(4). c = 2102.6(4) pm, β = 105.4(1)°, Z = 2. I: a = 1441.7(1). b = 1545.1(1). c = 2117.3(1) pm. β = 106.4(1)°, Z = 2. 3: a = 1004.4(1). b = 1378.8(1). c = 1899.3(2) pm. β = 94.2(1)°. Z = 4. The structures of I and 2 are very similar and consist of isolated cations and anions. The Sb8I28
4- ions of 1 and 2 and the anion of the same stoichiometry of (Ph4P)4Sb8I28 exhibit different struc­tures with a nearly identical Sb4I16 core. The anions of 3 are built up of polymeric cfiains.

Authors: Strauss Reinhard , Steudel Ralf 
Published: March 2015

Abstract
Titanocene pentasulfide reacts with sulfuryl chloride under suitable conditions to give a mixture of mainly S10, S15, and S20 which can be separated by repeated crystallization and precipitation. Pure S15 is obtained as a lemon-yellow powder at low temperatures which transforms to a sticky mass at 20 °C. Solutions of S15 in CS2 are stable at 20 °C for months. Pure S15 does not decompose at 20 °C within a few hours. Raman spectra of S15 show stretching vibrations at 409-480 cm-1 and bending and torsional modes at < 270 cm-1.

Abstract
The crystal structure of the triclinic compound Ag4(NH3)5Mo(CN)8- 1,5H2O could be refined in space group P1̄ (at T = 179 K: a = 974.6, b = 1477.6, C = 775.5 pm, α = 102.5, β = 94.6, y = 81.5°, Z = 2. Rg = 0.044 for 2744 independent reflections). The [Mo(CN)8]4_-groups form distorted square antiprisms with mean distances Mo-C = 215.7, C-N = 115.1 pm. They are connected to a puckered layer via four of their nitrogen ends which are tetrahedrally coordinated to silver (Ag-N = 226.7 pm). In between these layers and more or less tightly coordinated to their free cyano-N atoms dumbbells [CNAgNH3] and [Ag(NH3)2]+ are embedded. Their variation of distances and angles (Ag-N: 213 ... 216 pm, N-Ag-N: 150 ... 174°) is discussed.

Published: March 2015

Abstract
Cyclization of two diphenylacetylene molecules occurs if [(cod)RhCl] 2 (cod = 1.5-cyclooc-tadiene) is treated with methyllithium in the presence of tolane. The isolated (cod)Rh complex 2 contains an exo-methyl-tetraphenylcyclobutenyl ligand and was characterized by X-ray diffraction analysis. Thermolysis of 2 in acetonitrile causes ring expansion of the methylcyclobutenyl unit with formation of the tretraphenylcyclopentadienyl complex 3 together with 3-methyl-tet-raphenylcyclobutene. Mechanistic aspects are discussed as well as spectroscopic data of the new compounds.

From a saturated solution of EtOC6H4N2NHN2C6H4OEt in aqueous ammonia and Cu(NH3)4
2+ dark brown Cu(EtOC6H4N5C6H4OEt)2 (1) is obtained as an explosive precipitate. Upon heating in pyridine 1 is reduced to trimeric 1,5-bis(p-ethoxyphenyl)pentaazadienido copper(I) (2). 2 forms air-stable red crystals with the rhombohedral space group R3̄̄ and the lattice constants a = 1371.2(4) pm, α = 86.88(3)° and Z = 2. In 2 a linear Cu3
3+ chain is coordinated by the atoms N 1, N 3 and N 5 of three pentaazadienido ligands, such that each Cu atom obtains a trigonal planar coordination by three N atoms.
As 2 is located on the threefold axis of the space group R3̄̄, it has the Symmetrie C3. The distances Cu 2-N 3 = 192.7 pm to the more basic central atoms N 3 are shorter than the distances Cu 1-N 1 = 205.7 and Cu 3-N 5 = 201.5 pm to the outer N atoms of the N5 chains. The pentaazadienido ligand forms a planar N5 zig-zag chain with distances in the range of 127.8 to 135.4 pm. The very short Cu-Cu distances of 234.8 and 236.1 pm can be explained by bonding interactions between the d10 centers.

The labile acetone ligand is easily displaced by pyridine, cyclohexylisonitrile, phosphane and arsane donor molecules. X-ray diffraction analysis of [(dmb)2Ir(AsPh3)]BF4 reveals tetragonal pyramidal coordination at the iridium atom with the arsane ligand in axial position and with isolated BF4 anions. Spectroscopic data of the new [(dmb)2IrL]BF4 compounds are discussed and related with metal-ligand bond interactions.

The structure contains isolated “trimers” of one HCNB acceptor which is “pancaked” by two TDMAB neighbors. The arrangement of these trimers in the lattice results in alternating HCNB and TDMAB sheets. The solid is diamagnetic.

Abstract
New binucleating ligands, (L1) N ,N′,N″,N‴-tetrakis(2-benzimidazolylmethyl)-1,4,9,12-tetra-azacyclohexadecane, and (L2) N ,N′,N″,N‴-tetrakis(2-benzimidazolylmethyl)-1,4,11,14-tetra-azacycloeicosane were prepared. From the reaction mixture of copper(II) salt and the ligand, new binuclear copper(II) complexes, Cu2(L1) (NO3)4 (1), Cu2(L2)(NO3)4 (2), Cu2(L2)Br4 (3), and trinuclear complexes, Cu3(L1)Cl6 (4), and Cu3(L2)Cl6 (5) were obtained. Cyclic voltammograms revealed that the trinuclear complexes 4 and 5 are composed with the binuclear complex (1 or 2) and [CuCl4]2-. The interaction between two metal ions in the binuclear complexes are confirmed on the basis of the ESR spectra. These binuclear complexes exhibit higher catalytic activity for the oxidation of TMPD by O2 molecule than those of structurally rigid binuclear copper(II) complexes and of flexible binuclear complexes in which two copper(II) coordination sites are linked by a single polyatomic chain.

In order to elucidate specific properties of nickel sulfur complexes, reactions of recently synthesized [Ni('S5')], [Ni('OS4')]2, [Ni('NHS4')]2, [Ni('S4-C5')]2 and [Ni('S4-C3')] were investigated ('OS4'2- = 2,2'-bis(2-mercaptophenylthio)diethylether(2-), 'NHS4'2- = 2,2'-bis(2-mercaptophenylthio)diethylamine(2-), 'S5'2- = 2,2'-bis(2-mercaptophenylthio)diethylsulfide(2-), 'S4-C5'2- = 1,5-bis(2-mercaptophenylthio)pentane(2-), 'S4-C3'2- = 1,3-bis(2-mercaptophenylthio)propane(2-)).
Reactions with proton acids, CH3COCl and cyanide led to de-coordination of the sulfur ligands, thus providing a convenient synthesis of multidentate thioether-thiolate ligands.
The reactions of these Ni complexes with metal salts or metal complexes led to ligand transfer from nickel to Pd(II), Mo(IV ) and Hg(II), [Pd('S4-C3')], [Hg('S5')], [Hg('S4-C3')]. [Hg('S4-C5')], [Mo(O)('S5')], [Mo(O)('NHS4')] and [Mo(O)('OS4')] were synthesized by this method. X-ray structure analysis proved that [Mo(O)('OS4')] and [Mo(O)('NHS4')] have a pseudooctahedral Mo coordination with cis-thiolate atoms and trans-ether or amine and oxogroup donors.
Template alkylation of [Fe(CO)2(S2C6H4)2]2- by 3-(N, N-bis-(2-bromoethyl)-amino)-propionic acid methyl ester leads to a multidentate ligand that contains functional groups in the side chain.

The crystal structure of anhydrous lithium formate, published recently by Kansikas and Hermansson, is in fact that of a quenchable high-temperature modification (LiHCOO-I). The low-temperature modification LiHCOO-II can be obtained by thermal dehydration of the monohydrate, LiHCOO · H2O , or by drying it over P4O10. LiHCOO-II persists up to 228 °C, at which temperature it transforms to LiHCOO-I, which in turn is stable up to its melting point at 272 °C. LiHCOO-I is also the modification which crystallizes when a melt of lithium formate is cooled down, in spite of the fact that solidification occurs only at 165 °C, i.e. at a temperature well within the stability region of LiHCOO-II. The Raman spectra of the different forms of lithium formate are discussed in some detail.
Single crystals of LiHCOO-II, obtained by slow evaporation of a saturated solution of anhydrous LiHCOO in absolute methanol, are hexagonal, space group P63, with a = 14.915(2) Å, c = 5.543(1) Å and Z = 18. All lithium atoms are tetrahedrally coordinated by oxygen. The LiO4 tetrahedra are connected by corner-sharing and by bridging formate groups to form a complicated three dimensional network comprising tunnels running along [0 0 0 1 ]. No indications for an at least partial occupation o f these tunnels have been found.
