The Run centre is six-coordinated in a distorted octahedral arrangement, with the two Cl atoms located in the axial positions, and the pyridine (py) N atom, the two imino N atoms and the triphenylphosphine P atom located in the equatorial plane. The two equatorial Ru-N-imino distances (mean 2.093 angstrom) are substantially longer than the equatorial Ru-N-py bond [1.954 (4) angstrom]. It is observed that the N-imino-M-N-py bond angle for the five-membered chelate rings of 2,6-bis(imino)pyridine-based 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 intramolecular pi-pi stacking interactions between the aromatic rings belonging to the triphenylphosphine ligand and the dimethylaminophenyl fragment. The intermolecular 2 hydrogen bonds form an R-2(2)(12) ring and a zigzag chain of fused centrosymmetric rings running parallel to the [100] direction.eninfo:eu-repo/semantics/closedAccessEthylene PolymerizationRuthenium(Ii) ComplexesCobalt CatalystsIronLigandsCyclopropanationOlefinsArticle63M264M26610.1107/S0108270107021610N/AWOS:0002479812000112-s2.0-3425000497217551185N/A
