Metal complexes of sulphur ligands. Part VIII. Crystal and molecular structure of cis-bis(diethylphosphinodithioato)bis(dimethylphenylphosphine)ruthenium(II)

Abstract

The structure of [Ru(S₂PEt₂)₂(PMe₂Ph)₂] has been determined by X-ray diffraction analysis. Reflections were collected from Weissenberg photographs along two axes, using a SAAB automatic film scanner. Crystals are orthorhombic, space group Pbca, with Z= 8 in a unit cell of dimensions: a= 17·88(4), b= 20·92(5), c= 17·31(3)Å. The structure was solved by standard methods, and refined to R 8·2% for 1387 observed reflections. The Ru–S bonds trans to phosphorus are significantly longer than the others.
