摘要：

Double complex salts (DCS) [RuNO(NH3)4(H 2O)]2[MCl4]Cl4·2H 2O, M = Pt (I) and Pd (II), are prepared and characterized using IR spectroscopy, single crystal and powder X-ray diffraction, and thermogravimetric analysis. Crystalline phases of I and II are isostructural (P2(1)/n space group) and have the following crystallographic characteristics: a = 6.689 Å, b = 15.609 Å, c = 12.348 Å, V = 1289.1 Å3, Z = 2, dx = 2.425 g/cm3 (I) and a = 6.637 Å, b = 15.521 Å, c = 12.244 Å, V = 1261.2 Å3, Z = 2, dx = 2.255 g/cm3 (II). The thermolysis of the obtained DCS in the hydrogen atmosphere affords two-phase mixtures of limited solid solutions of the metals: hcp for ruthenium-based ones and fcc for Pt or Pd based solutions. On decomposition in the helium atmosphere the products contain a minor amount of RuO2. For the phases obtained during thermolysis the parameters are determined and the compositions are estimated. The heating of I to 400°C in the helium-air atmosphere yields a nanocrystalline composite Pt+RuO2 with CSR of ∼20 nm. © 2011 by O. A. Plyusnina, V. A. Emel'yanov, I. A. Baidina, P. E.
