Synthesis and crystal structure of a disubstituted nickel(II) bis-[(di-methyl-amino-phenyl-imino)-eth-yl]pyridine chloride complex.

ABSTRACT: The solvated title compound, bis-[2,6-bis-(1-{[4-(di-methyl-amino)-phen-yl]imino-?N}eth-yl)pyridine-?N]nickel(II) dichloride-di-chloro-methane-water (1/2/2), [Ni(C25H29N5)2]Cl2·2CH2Cl2·2H2O, represents a nickel(II) bis-(pyridine di-imine) complex with electron-donating di-methyl-amino-phenyl substituents. The complex crystallizes as a water/di-chloro-methane solvate with Z' = 2, thus the asymmetric unit consists of two NiII complex cations, four chloride anions, four adventitious water and four di-chloro-methane solvent mol-ecules. Around each octa-hedrally coordinated NiII cation, one pendant phenyl group on each of the two ligands has an intra-molecular ?-? inter-action with the pyridine ring of the other chelating ligand. In the crystal, pairs of water mol-ecules are hydrogen bonded to pairs of chlorine atoms. The di-chloro-methane solvent mol-ecules are likewise hydrogen bonded to the chloride anions.
