Abstract
SYNTHESIS OF COPPER COMPLEXES OF SCHIFF BASE LIGANDS CONTAINING NITROGEN, OXYGEN AND SULPHUR DONOR ATOMS AND THEIR SPECTROSCOPIC CHARACTERIZATION

Neha Tripathee and *Sulekh Chandra

ABSTRACT

Cu (II) complexes are synthesized with 2 ligands, pyridine-2-carboxyaldehyde thiosemicarbazone and pyridine-2-carboxyaldehydesemicarbazone respectively. These complexes have been characterized on the basis of their elemental analysis, molar conductance, magnetic susceptibility and electronic, Nuclear Magnetic Resonance and Mass spectroscopic studies. The complexes in DMSO have been found to possess molar conductance between 5-10 Ω-1 Cm2mol-1 with Ligand 1 and between 130-185 for ligand 2,indicating their nonelectrolytic and 1:2 electrolytic nature respectively. Ligand 1(Pyridine-2-carboxyaldehydethiosemicarbazone) has been found to be bidentate on the basis of IR spectral studies and thus the complexes with it have been formulated as [Cu(L1)2X2]. Lligand 2 (Pyridine-2-carboxyaldehydesemicarbazone) is found to be tridentate, and complexes with it, can be formulated as [Cu(L2)2]X2.Where X= Cl‑, Br-, SCN-, ClO4-. Spectroscopic studies have revealed tetragonal geometry for all the complexes and paramagnetic nature with one unpaired electron.

Keywords: Copper (II) complexes, Spectrocsopic studies, Thiosemicarbazone and semicarbazone.
