Transition metal complexes of cobalt(II), nickel(II), copper(II) and zinc(II) of isatinimine Schiff base ligands (HL₁-HL₂) derived from isatin 5-chloro-2-hydroxy aniline (HL₁), 2-amino-4-nitrophenol (HL₂) and heterocyclic nitrogen base 8-hydroxyquinoline have been synthesized. All the metal complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility, SEM and spectroscopic techniques (IR, UV-visible, NMR and ESR). Transition metal complexes existed as octahedral or distorted octahedral geometries around metal centres with the donation of carbonyl oxygen, azomethine nitrogen and deprotonated enolic oxygen, whereas ligand 8-hydroxyquinoline existed as monobasic bidentate ON coordinating through oxygen of hydroxyl group and nitrogen of quinoline ring. The complexes were found to be non-electrolytic in nature.
