(η(6)-Benzene){2-[2-(tert-butyl­sulfan­yl)phenyl]pyridine-κ(2) N,S}chlorido­ruthenium(II) hexa­fluorido­phosphate

In the title compound, [RuCl(C(6)H(6))(C(15)H(17)NS)]PF(6), the cation adopts a three-legged piano-stool structure around the Ru(II) atom with an η(6)-benzene ligand, a chloride ligand and a 2-[2-(tert-butyl­sulfan­yl)phen­yl]pyridine (btppy) ligand. The btppy ligand acts as a N,S-bidentate ligand, forming a six-membered ring, which has an envelope conformation. The S—Ru—N bite angle is 86.76 (9)°, and the dihedral angle between the pyridine and benzene rings in btppy is 39.8 (2)°. The unit cell contains two pairs of racemic diastereomers with (S (Ru),S (S)) and (R (Ru),R (S)) configurations, in which the tert-butyl group on the coordin­ated S atom is distant from the η(6)-benzene ligand.
