Abstract
SYNTHESIS OF LIGAND USING PYRIDINE -2-CARBOXYALDEHYDE AND SPECTROSCOPIC CHARACTERIZATION OF THEIR COBALT (II) COMPLEXES

Neha Tripathee and Sulekh Chandra*

ABSTRACT

Co(II)Complexes have been synthesized with the ligand pyridine-2-carboxyaldehydethiosemicarbazone.The ligand and complexes have been characterized by elemental analysis, determination of melting point, molar conductance and magnetic susceptibility, Mass spectra, infrared and UV spectral studies. The molar conductance measurements in DMSO lies in the range of 7-11 Ω-1 Cm2mol-1 ,which suggest the complexes to be non elctrolyte in nature and being formulated as [M(L)2X2].Where X= Cl‑, Br-,I-, SCN-, ClO4- .The IR and other spectroscopic studies suggest bidentate nature of the ligand and the octahedral geometry of the complexes.

Keywords: Copper (II) complexes, Pyridine-2-carboxyaldehydethiosemicarbazone, spectroscopic studies.
