Synthesis and crystal structure of a disubstituted nickel(II) bis­[(di­methyl­amino­phenyl­imino)­eth­yl]pyridine chloride complex

The solvated title compound, bis­[2,6-bis­(1-{[4-(di­methyl­amino)­phen­yl]imino-κN}eth­yl)pyridine-κN]nickel(II) dichloride–di­chloro­methane–water (1/2/2), [Ni(C(25)H(29)N(5))(2)]Cl(2)·2CH(2)Cl(2)·2H(2)O, represents a nickel(II) bis­(pyridine di­imine) complex with electron-donating di­methyl­amino­phenyl substituents. The complex crystallizes as a water/di­chloro­methane solvate with Z′ = 2, thus the asymmetric unit consists of two Ni(II) complex cations, four chloride anions, four adventitious water and four di­chloro­methane solvent mol­ecules. Around each octa­hedrally coordinated Ni(II) cation, one pendant phenyl group on each of the two ligands has an intra­molecular π–π inter­action with the pyridine ring of the other chelating ligand. In the crystal, pairs of water mol­ecules are hydrogen bonded to pairs of chlorine atoms. The di­chloro­methane solvent mol­ecules are likewise hydrogen bonded to the chloride anions.
