A series of salicylketimines (2-[(2,6-diisopropylphenylimino)ethyl]phenol, 2-[(2,6-diisopropylphenylimino)ethyl]naphthol and 2-[(2,6- diisopropylphenylimino)(phenyl)-methyl]phenol), and their nickel complexes of general forms [(salicylketiminato)-Ni(PPh3)(Ph)] and [(salicylketiminato)2Ni] were synthesized and characterized. The formation of monophenyl-nickel(II) complexes versus the corresponding bis(sal)Ni(II) complexes depends on the fine tuning of the reaction work up and is affected by the substituent at the ketimine. Salicylketimines were thus found to form more readily the bis(sal)Ni(II) complexes than salicylaldimines. The molecular structures of the complexes were determined by X-ray crystallography and in all of them Ni has a nearly ideal square-planar coordination sphere.
