Ruthenium trichloride, obtained from its hydrate with thionyl chloride, reacts with excess trichloronitrom ethane yielding polymer [Ru(NO)Cl₃]; by addition of triphenylmethylphosphonium chloride in dichlorom ethane (PPh₃Me)₂[Ru(NO)Cl₄]₂ · 2 CH₂Cl₂ is obtained, the IR spectrum of which is reported and assigned. Its crystal structure was determined with X-ray diffraction data (6404 independent observed reflexions, R = 0.068). Crystal data at -90 °C: a = 1145, b = 1591, c = 1406 pm, β = 96,0°, Z = 2, space group P2₁/C. The structure consists of PPh₃Me⊕ cations, centrosymmetric anions [Ru(NO)Cl₄]₂²⊖ nearly fulfilling C₂ₕ symmetry, and CH₂Cl₂ molecules. In the anions the Ru atoms are linked via chloro bridges; the nitrosyl groups occupy axial positions with bond distances RuN of 175 and NO of 113 pm, bond angle RuNO 172.7°.
