Özet
In the title compound, [RuCl2(C2H3N)(C27H31N3)]·0.5CH2Cl2, the RuII 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 dichloromethane solvent molecule lies on a twofold axis. The two equatorial Ru—Nimino distances are almost equal (mean 2.089 Å) and are substantially longer than the equatorial Ru—Npy bond [1.914 (4) Å]. It is observed that the Nimino—M—Npy bond 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 intermolecular C—H⋯Cl hydrogen bonds. The intermolecular hydrogen bonds form an R66(24) ring and a chain of edge-fused rings running parallel to the [001] direction.
