title: Bis(di-2-pyridyl sulfide-kappa2N,N')(4-methylpyrimidin-2-yl 2-pyridylmethyl sulfide-kappa2N,S)ruthenium(II) bis(hexafluorophosphate) acetonitrile solvate.
abstract: The crystal structure of the title compound, [Ru(C10H8N2S)2(C11H11N3S)](PF6)2.C2H3N, is composed of a bivalent octahedral RuII complex, two PF6- anions and an acetonitrile solvent molecule. Two PF6- units are found on a crystallographic binary axis, therefore contributing just one half each to the asymmetric unit cell. The structure displays a peculiar stereochemistry of the cation. Three bidentate ligands around the Ru centre, together with the coordination of the non-symmetric S atom, mean that these two atoms are chiral. This would lead to four stereoisomers, but only an enantiomeric pair was found in the analyzed sample.
