X-ray diffraction is applied to study a new crystalline modification of K2[Pd(NO3)4]-β-K2[Pd(NO3)4]. It is found that the phase is isostructural with Na2[Pd(NO3)4] and Rb2[Pd(NO3)4]. Square coordination of the Pd atom is formed by oxygen atoms of monodentately coordinated nitrate groups.

At T 150 K the crystal structure of [Rh(NH3)5Cl]WO4 is studied: a = 11.2374(4) Å, b = 8.4857(3) Å, c = 10.5326(3) Å, V = 1004.36(6) Å3, space group Pnma, Z= 4, d x = 3.117 g/cm3. In the structure, complex ions are bound by N—H…O hydrogen bonds, with the shortest ones of 2.85–2.94 Å. Ionic packing is shown to be considered as rhombohedral with a t ≈ 5.26 Å, αt ≈ 106°. Thermal properties of the salt are studied in the hydrogen atmosphere. The product of thermal decomposition at 750°C is a mixture of three solid solutions of Rhx W 1- x based on fcc, bcc, and hcp structures. All the obtained phases are nanocrystalline. The sizes of coherent scattering regions are 10–12 nm. 相似文献

Complex salts [Ir(NH3)5Cl]x[Rh(NH3)5Cl]1−x
MO4 (x = 0.5, 1; M = Mo, W) are synthesized and their thermal properties are studied. The crystal structures are determined for
[Ir(NH3)5Cl]WO4 and [Ir(NH3)5Cl]MoO4. In the structures, the ions are linked by N-H...O hydrogen bonds, the shortest ones being 2.868(2)–3.422(2) ?. and 2.860(4)–3.434(3)
?. respectively. The thermal properties of the complex salts are studied in the hydrogen atmosphere and in hydrogen-helium
mixtures. It is demonstrated that the final products are the mixtures of nanocrystalline powders of Ir and binary or ternary
solid solutions with the hcp lattice. 相似文献

The structures of two isostructural phases of [M(Еn)3](ReO4)2 (M = Ni, Zn; Еn is ethylenediamine) are studied. The crystal structures belong to the triclinic system, but demonstrate a pseudohexagonal packing motif. It is shown that the product of thermal decomposition of [Zn(Еn)3](ReO4)2 (hydrogen atmosphere, 400 °C) is a homogeneous mixture of nanocrystalline zinc and rhenium powders with coherent scattering regions of ~30 nm. 相似文献

By single crystal X-ray diffraction the structures of [CuEn2][Pt(NO2)4] and [PdEn2][Pt(NO2)4] are determined. In the structures, the main structural moieties are identified. It is shown that the structure of [PdEn2][Pt(NO2)4] can be considered as quasi-one-dimensional: in the Y axis direction, the stacks of alternating complex cations and anions locate. 相似文献

Reactions of nitrite complexes of Pd, Ru, and Rh with sulfamic acid were studied by the 14, 15N, and 17O NMR method. Chemical shifts were assigned, and the predominant forms of the complexes were established. The reaction products at room temperature are cis-nitroaqua complexes. Coordination of the sulfamate ion upon storage for a long time or on heating was detected. 相似文献

An integrated Xray diffraction study was performed on polycrystals and single crystals of three new isostructural phases with general formula Ag4A2[M(NO2)4]3 (M = Pd, Pt; A = K, Rb). Data on the crystal structure solution (CAD4 diffractometer, MoK
radiation, graphite monochromator = 2–30° are presented. In one crystallographically independent [M(NO2)4]2- complex anion, the planar square coordination of the central atom is completed to 4 + 2 by two oxygen atoms at a distance of 3.02–3.12 in the other anion, it is completed to 4 + 1 + 1 by an oxygen atom at a distance of 3.12–3.30 and an Ag+ cation at a distance of 3.04–3.11 . Part of the Ag+ cations form Ag - Ag dimers with a distance of 3.03–3.07. Crystalchemical analysis of known structures containing [Pd(NO2)4]2- complex anions was performed. It has been established that in none of the cases do any of the possible limiting configurations occur. 相似文献
