Bis(di-2-pyridyl sulfide-κ2N,N′)(4-methylpyrimidin-2-yl 2-pyridylmethyl sulfide-κ2N,S)ruthenium(II) bis(hexafluorophosphate) acetonitrile solvate

The crystal structure of the title compound, [Ru(C 10 H 8 N 2 S) 2 -(C 11 H 11 N 3 S)](PF 6 ) 2 .C 2 H 3 N, is composed of a bivalent octahedral Ru II complex, two PF 6 - anions and an acetonitrile solvent molecule. Two PF 6 - 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.
