title: Partially oxidized ruthenium phosphine thiolates: [Ru(pySO2)0.33(pyS)1.67(dppe)] and [Ru(pySO2)0.355(pyS)1.645(dppp)].
abstract: The crystal structures of [1,3-bis(diphenylphosphino)ethane-kappa2P,P'](pyridine-2-sulfinato-kappa2N,S)(pyridine-2-thiolato-kappa2N,S)ruthenium(II), [Ru(C5H4NO2S)0.33(C5H4NS)1.67(C26H24P2)] or [Ru(pySO2)1-x(pyS)1+x(dppe)] (x=0.67), (I), and [1,3-bis(diphenylphosphino)propane-kappa2P,P'](pyridine-2-sulfinato-kappa2N,S)(pyridine-2-thiolato-kappa2N,S)ruthenium(II), [Ru(C5H4NO2S)0.355(C5H4NS)1.645(C27H26P2)] or [Ru(pySO2)1-x(pyS)1+x(dppp)] (x=0.645), (II), are composed of neutral distorted octahedral RuII complexes with chelating pyridine-2-thiolate, pyridine-2-sulfinate and biphosphine ligands. The S atoms are trans to each other, while pairs of P and N atoms are in cis positions. Partial double-bond character is observed for C-S. The crystal packing consists of monolayers stabilized by C-H...O and C-H...S interactions, and is affected by the alkyl-chain lengths.
