(Acetonitrile){2,6‐bis­[1‐(2‐ethyl‐6‐methyl­phenyl­imino)­ethyl]­pyridine}­dichloro­ruthenium(II) dichloro­methane hemisolvate: a chain of edge‐fused R66(24) rings

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