Abstract

The molecular and crystal structures of the title complex, [Ru(C10H8N2)(C12H9NO)(C2H6OS)2](CF3O3S)2 or cis(S),trans(O,N bpy)-[Ru(bpy)(ppk)(dmso-S)2](OTf)2 {bpy = 2,2′-bipyridine, ppk = phenyl-2-pyridyl ketone [IUPAC nomenclature: phenyl(pyridine-2-yl)methanone], dmso = dimethyl sulfoxide, and OTf− = trifluoromethanesulfonate}, are reported. The Ru2+ ion has a distorted octahedral geometry with two bpy N atoms, the N and O atoms of ppk, and two S atoms of two cis dmso-S ligands. The carbonyl O atom of ppk is trans to bpy, and the N atom of pyridyl is trans to the dmso-S ligand [trans(O,N bpy) geometry]. One of the trifluoromethanesulfonate anions is disordered over three positions, with occupancies of 0.4, 0.4, and 0.2, respectively, in the refined model. The original disordered and SQUEEZE [Spek (2015). Acta Cryst. C71, 9–18] models were found to be almost equivalent, indicating that both the SQUEEZE and the original disordered model are satisfactory.
