(Acetonitrile){2,6-Bis[1-(2,4,6-Trimethylphenylimino)Ethyl]Pyridine}Dichloridoruthenium(II) Dichloromethane Solvate

Abstract

In the title compound, [RuCl2(C2H3N)(C27H31N3)]·CH2Cl2, the Ru II ion is six-coordinated in a distorted octa-hedral 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 - Nimino distances are almost equal (mean 2.087 Å) and are substanti-ally longer than the equatorial Ru - Npy bond [1.921 (4) Å]. It is observed that the Nimino - M - Npy angle for the five-membered chelate rings of pyridine-2,6-diimine complexes is inversely related to the magnitude of the M - Npy bond. The title structure is stabilized by intra- and inter-molecular C - H⋯Cl hydrogen bonds, as well as by van der Waals inter-actions. © International Union of Crystallography 2007.
