The cationic complex of the title salt, [Ru(C19H13N5)2](PF6)2·3C4H10O, has the Ru atom in a slightly distorted octahedral environment of two tridentate benzimdazolyl-pyridine ligands and displays extensive π–π and C—H⋯π interactions.
The title compound, [Ru(C19H13N5)2](PF6)2·3C4H10O, was obtained from the reaction of Ru(bimpy)Cl3 [bimpy is 2,6-bis(1H-benzimidazol-2-yl)pyridine] and bimpy in refluxing ethanol followed by recrystallization from diethyl ether/acetonitrile. At 125 K the complex has orthorhombic (Pca21) symmetry. It is remarkable that the structure is almost centrosymmetric. However, refinement in space group Pbcn leads to disorder and definitely worse results. It is of interest with respect to potential catalytic reduction of CO2. The structure displays N—H⋯O, N—H⋯F hydrogen bonding and significant π–π stacking and C—H⋯π stacking interactions.
