SPECTROSCOPIC STUDY AND SYNTHESIS OF SCHIFFS BASE LIGAND OF 2-BENZOYLPYRIDINE SEMICARBAZIDE HYDROCHLORIDE AND ITS Cu(II) AND Ni(II) TRANSITION METAL COMPLEXES

Transition metal complexes of Cu(II) and Ni(II) with 2-benzoylpyridinesemicarbazide hydrochloride with general composition ML2X2 (where M= Cu(II) and Ni(II), L= 2-benzoypyridine and semicarbazide hydrochloride ligand, X= Cl-,NO3-, SO42-, OAc- have been synthesised and characterised by elemental analysis, magnetic moment, conductivity measurement, mass spectrometry, IR spectrometry, UV-Vis spectroscopy, and EPR spectral studies. The magnetic moment values indicate that these are high spin complexes. The IR spectral study indicates that ligand is bidentate and coordinated through N and O. On the basis of spectral study Octahedral geometry was proposed for Ni(II) complexes and tetragonal geometry was proposed for Cu(II) complexes.
