Abstract :This article describes the synthesis of isonitrosomethyl-p-tolyl ketone [HL] as the starting material and then we prepared the schiff base ligand from the reactions of the amine compounds with o- phenylenediamine [ H 2 L 1 ]. A new series of mono-, homo and heterodinuclear copperinsert ignore into journalissuearticles values(II);/nickelinsert ignore into journalissuearticles values(II); complexes have been synthesized using an oxime ligand. The complexes were characterized by IR, elemental analysis, magnetic moment measurements, molar conductivity, mass spectra and TGA studies. The free ligand were also described 13 C and 1 H-NMR spectra. For complexes using stoichiometric and spectroscopic data of the metal complexes showed that metal:ligand ratio of mononuclear copperinsert ignore into journalissuearticles values(II); complex was found to be 1:1 while this ratio was 2:1 in homo- and heterodinuclear copperinsert ignore into journalissuearticles values(II); complex and 3:2 in the trinuclear copper insert ignore into journalissuearticles values(II); complex and metal ions are coordinated to the imine and oxime nitrogen atoms.
