(Acetonitrile){2,6-bis[1-(2,4,6-trimethylphenylimino)ethyl]pyridine}dichloridoruthenium(II) dichloromethane solvate

Abstract

In the title compound, [RuCl2(C(2)H(3)N)(C(27)H(31)N(3))].CH(2)Cl(2), the Ru(II) ion is six-coordinated in a distorted octahedral arrangement, with the two Cl atoms located in the apical positions, and the pyridine (py) N atom, the two imino N atoms and the acetonitrile N atom located in the basal plane. The two equatorial Ru-N(imino) distances are almost equal (mean 2.087 A) and are substantially longer than the equatorial Ru-N(py) bond [1.921 (4) A]. It is observed that the N(imino)-M-N(py) angle for the five-membered chelate rings of pyridine-2,6-diimine complexes is inversely related to the magnitude of the M-N(py) bond. The title structure is stabilized by intra- and intermolecular C-H...Cl hydrogen bonds, as well as by van der Waals interactions.
