Synthesis and characterization of new homo and heteronuclear schiff base copper(II) complexes

Abstract

This article describes the synthesis of isonitrosomethyl-p-tolyl ketone [HL] as the starting compound and then we prepared the new oxime ligand from the reactions of the amine materials with 1,2-diaminobenzene [H2L1]. (1E, 2E, 1'E, 2'E)-3,3'-bis [(4-tolyl ketone)-(1,2 phenylene diimine)]. Acetaldehyde dioxime ligand was used to synthesize the metal complexes. The complexes were elucidated by FT-IR, elemental analysis, magnetic moment measurements, molar conductivity, mass spectra, and TGA studies. The free ligand was also described with its13C and1H-NMR spectra. For complexes using spectroscopic and stoichiometric data of the complexes showed that metal:ligand ratio of mononuclear copper(II) complex was found to be 1:1 while this ratio was 2:1 in homo-and heterodinuclear copper(II) complex and 3:2 in the trinuclear copper(II) complex. All these data show us that the proposed structure is consistent with the obtained data. © 2018, Turkish Chemical Society. All rights reserved.
