Abstract
By reaction of Pb(CH3COO)2 · 3H2O with Na2S2C=C(CN)2 · 3H2O in water, α-PbS2C=C(CN)2 is obtained. Hydrothermal conditions give small crystals of the α-and β-phase.

The crystal structure of the last compound, ([2](1,5)naphthalino[2]paracyclophane)silver(I) Perchlorate, has been determined by X-ray methods. It crystallizes in the centrosymmetrical space group P21/n with cell dimensions a = 12.495(2), b = 8.546(1), c =16.196(2) Å, β = 101.27(1)°. Both enantiomers of the ligands are present in the unit cell and related by centrosymmetry. Each silver atom is connected with the naphthalin systems of two ligands and with two Perchlorate anions, one of which is chelating, while the other is only monodentate. The cation/anion chains are linked through the organic ligands in such a way that a sheet structure is formed. The benzene rings of the cyclophanes are not involved in the metal coordination, the naphthaline rings are μ3 -bonded to the silver atoms, which are not ring-centered.

Polymorphie von Tellur(IV)-iodid/ Polymorphism of Tellurium(IV) Iodide
Authors: Kniep Rüdiger , Beister Heinz Jürgen , Wald Dieter 
Published: March 2015

Abstract
Idiomorphous crystals of five different polymorphic modifications (α-ε) of TeI4 are simultaneously grown from solutions of TeI4 and concentrated HI in methanol by evaporating the solvent at room temperature. δ-TeI4 is the only stable phase at normal conditions. Phase transformations of α-, β-, γ-and ε-TeI4 to the final stage δ-TeI4 take place by heating and run through discrete intermediates. The observed graduations lead to a sequence γ-, β-, α-,ε-TeI4 which indicates “increasing metastability”. The crystal structures of α-TeI4 (trigonal; P3̄ml; a = 4.228(2), c - 6.684(6)Å, Z = 0.5; Dx = 5.10 g/cm 3), β-TeI4 (orthorhombic; Pn21m; a = 6.888(2), b = 14.539(3), c = 16.753(4) Å, Z = 8; Dx = 5.03 g/cm3) and γ-TeI4 (monoclinic; P21/c; a = 11.199(4), b = 13.599(4), c = 22.158(6) Å,β = 98.10(3)°, Z = 16; D, = 5.05 g/cm3) are related to the known crystal structure of δ-TeI4. α-TeI4 (“Te0.5I2”) is an isotype of the 2H-CdI : structure with random distribution of Te over the Cd-positions. The crystal structures of β-, γ-and δ-TeI 4 contain discrete tetrameric molecules “(TeI4)2 (TeI3
+I-)2” which are generated by ordered distributions of Te over 1/4 of the octahedral holes of a 2H-(β) and a 4H-sequence (y,δ ) of the nearly close packed iodine layers. A nearly cubic close packing of Iodine atoms is observed in the crystal structure of ε-TeI4 (tetragonal; I41/amd; a = 16.875(6), c -11.829(5) Å, Z = 16; Dx = 5.01 g/cm 3). The ordered distribution of Te in 1/4 of the octahedral holes leads to tetrameric molecules “(TeI3
+I-)4” in a cubanelike arrangement which, thus far, has been observed only in the crystal structures of TeCl4 and TeBr4 . The Madelung Parts of Lattice Energies, MAPLE, of β-, γ-, δ-and ε-TeI4 are calculated.

Abstract
The ratios of reduced and oxidized nicotinamide nucleotides (NADH/NAD+ and NADPH/ NADP+) were indirectly determined at various stages of cataractogenesis by estimating the concentrations of metabolites (lactate, pyruvate and malate) of the lens. The ratios of NADH/NAD+ and NADPH/NADP+ decreased significantly from immature to mature (P<.001, P<.05). to hypermature (P<.001, P<.05), to Morgagnian (Pc.001. Pc.001) and diabetic types (Pc.001, P < .001) of cataractous lenses respectively. Ratios of nicotinamide nucleotides in diabetic lenses were lower in comparison to those of other types studied. As the opacity progressed, the ratios decreased with increase in blood glucose levels.

Abstract
Hexa-terf-butyldisiloxane (tBu3Si)2O (2), hexa-rerr-butyldisilazane (tBu3Si)2NH (3), and the disiloxane (tBu3SiNHSuBu2)2O (4) are prepared from bis(silyl)triazene tBu3SiN=N-NHSirBu3 by reaction with water (2) and by thermolysis (3), or from silanimine tBu2Si=NSirBu3 by reaction with water (4). Structures of 2-4 have been determined by X-ray crystallography (for data cf. Tables II). As a consequence of the bulkiness of the silyl groups, the heavy atom frameworks SiOSi in 2 and 4 are linear, and the SiNSi angles in 3 (167 ± 2°) and 4 (157.1°) are comparatively large.

Abstract
The title compounds have been prepared by reactions of the metal acetates of zink, cadmium, and mercury with ethanolic solutions of sodium polyselenides in the presence of 15-crown-5. They form dark red crystals, which were characterized by their IR specta as well as by X-ray crystal structure determinations. All complexes [Na-15-crown-5]2[M(Se 4)2] with M = Zn (1), Cd (2), Hg (3) crystallize isotypically in the space group C2/c with 4 formula units per unit cell. In the anions [M(Se4)2]2- the metal atoms are coordinated tetrahedrally by four selenium atoms of two Se4
2- units, thus forming a spiro-bicyclus. The complex cations [Na-15-crown-5]+ have a Na---Se contact of approximately 299 pm with two selenium atoms of a MSe4 group, allowing formulation of triple ion species.
