A new mixed-ligand complex, Cd(S2CN(C4H9)2)2Phen, is synthesized and investigated by thermal, element, and IR analyses and by diffractometry of polycrystals (DRON-3M, CuKα radiation, Ni filter). The crystal structure was determined on a CAD-4 Enraf-Nonius automatic diffractometer (MoKα radiation, θ from 1.5 to 25?, 2325 nonzero independent reflections, 190 refined parameters, R = 0.036 for I > 2Σ(I)). Crystal data for C30H44CdN4S4 : a = 15.592(3), b = 22.724(5), c = 9.922(2) å, space group Pbcn, V = 3515.5(12) å3, Z = 4, M = 701.33, dcalc = 1.325 g/cm3. The structure involves monomeric molecules in which the cadmium atom has a distorted octahedral environment. 相似文献

The paper describes synthesis of (nBu4N)2[RuNOCl5](I), (nBu4N)2[RuNOCl4OH](II), (nBu4N)2×[RuNOCl4OH]·6H2O (III), and (nBu4N)2[RuNOCl5]· 2(nBu4N)2[RuNOCl4(H2O)]·2H2O (IV). The complexes were studied by IR spectroscopy and powder Xray and crystal Xray analyses. The structures are built up of [RuNOCl5]2- (I, IV), [RuNOCl4OH]2- (II, III), and [RuNOCl4(H2O)]- (IV) complex anions, (nBu4N)+ cations, and crystal water molecules (III, IV). The substances are moderately soluble in water; highly soluble in polar organic solvents, such as acetone, ethanol, chloroform, methylene chloride; and almost insoluble in carbon tetrachloride and toluene. Under storage in light, the compounds decompose from the surface; in darkness I and II are stable, whereas III and IV can lose part of the crystal water. 相似文献

Layers of [(CH3)3SiO]8(SiO1.5)8 and [(CH3)3SiO]12(SiO)6 organosilicon compounds obtained by chemical vapor deposition were investigated by X-ray diffraction (DRON-RM4, R = 192 mm, CuK
radiation) and Raman spectroscopy (Triplemate, SPEX). The layers were found to be ideally oriented polycrystalline films. The octakis-(trimethylsiloxy)octasilsesquioxane polycrystals are oriented in one crystallographic direction — [001], while the dodecakis-(trimethylsiloxy)cyclohexa-siloxane polycrystals are oriented in the
and
directions. Crystal structure analysis in these directions yielded the type of the planar lattice followed by the molecules and their orientation relative to the support.Original Russian Text Copyright © 2004 by S.

Two crystal modifications, I and II, of the ZnPhen(S2CNEt2)2 complex have been isolated. According to XRD data, the single crystals of I are triclinic with a=9.745(2), b=10.252(2), c=14.331(3) Å, α=99.18(2), β=91.01(2), γ=113.28(2)°, V=1293.2(4) Å3, space group P1, Z=2, dcalc=1.401 g/cm3. The crystals of II are monoclinic with a=7.220(6), b=18.095(2), c=19.050(4) Å, β=95.85(2)°, V=2475.8(7) Å3, space group C2/c, Z=4, dcalc=1.461 g/cm3. In both modifications, the structure is formed by monomer molecules with a distorted octahedral environment of the zinc atom. All atoms in I are in the general position; in II, the atoms are linked by the twofold rotation axis. It is shown by X-ray phase analysis (XRPA) that the MnPhen(S2CNEt2)2 complexes (III) are isostructural to modification I of the ZnPhen(S2CNEt2)2 complex, which underlies the synthesis of a solid solution of these complexes, MnZn2Phen3(S2CNEt2)6 (phase IV). It is found that MPhen(S2CNEt2)2 (M=Zn2+, Mn2+) and phase IV quantitatively sublime when heated in vacuum. Thermolysis of III in argon yields manganese(II) sulfide of cubic modification; the main product of thermolysis of phase IV is a solid solution of ZnxMn1?xS of hexagonal modification. 相似文献

Thick (≈0.2–1 μm) layers of octaorganylsilsesquioxanes [RSiO1.5]8, where R is CH3, C2H3, and C2H5, were obtained by vacuum deposition and studied by X-ray diffractometry (DRON-3M, R=192 mm, CuKα radiation). Irrespective of the type of support, the layers are ideally oriented polycrystalline films with the [001] texture
axis. Structural arrangement of the layers is analyzed on the basis of the crystal data. Orientation of the terminal atomic
groups on the surface of the layer is established. It is shown that it is possible to adjust the scale of the layer pattern.
Two-layer compositions— Cu(II) β-diketonates and phthalocyanines on octaorganylsilsesquioxane supports and vice versa — with
preserved orientations of the films were obtained.

An X-ray diffraction investigation has performed for copper(II) bis-hexafluoroacetylacetonate (Bruker AXS P4 automatic diffractometer, MoK
radiation, t = –25°C). Crystal data for C10H2CuF12O4: a = 5.530(1) Å, b = 6.038(1) Å, c = 11.266(2) Å, = 95.948(3)°, = 101.743(3)°, = 92.298(3)°, space group; P1, V = 365.6(1) Å3, Z = 1, d
calc = 2.169 g/cm3. The square-planar environment of the copper atom (Cu-Oav 1.912 Å, O-Cu-Oav 93°) is completed to bipyramidal by two fluorine atoms of the neighboring molecules, Cu...F 2.71 Å and 2.75 Å.Original Russian Text Copyright © 2004 by S.
