Crystal and molecular structure of thiocarbonylbis(triphenylphosphine)rutheniumtri-µ-chloro-chlorobis(triphenylphosphine)ruthenium

Abstract

Crystals of the title compound, CS(PPh₃)₂RuCl₃Ru(PPh₃)₂Cl, are orthorhombic, space group Pn2₁a with a= 21·53, b= 23·40, c= 14·20 Å. For 1258 independent reflections recorded on film, the final R was 0·115. Both ruthenium atoms have a distorted octahedral co-ordination, with the two octahedra sharing a common face defined by three chlorine atoms. The Ru ⋯ Ru distance is 3·35 Å. Two different molecular structures may exist in the crystal, differing in the relative positions of the thiocarbonyl and terminal chloro groups of the molecule.
