(η6-Benzene){2-[2-(tert-butylsulfanyl)phenyl]pyridine-κ2N,S}chloridoruthenium(II) hexafluoridophosphate

Abstract

In the title compound, [RuCl(C6H6)(C15H17NS)]PF6, the cation adopts a three-legged piano-stool structure around the Ru(II) atom with an η6-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 (SRu,SS) and (RRu,RS) configurations, in which the tert-butyl group on the coordinated S atom is distant from the η6-benzene ligand.
