SPECTROSCOPIC CHARACTERISATION AND SYNTHESIS OF Cu(II) AND Ni(II) COMPLEXES WITH NITROGEN AND SULPHUR DONOR BIDENTATE SCHIFF’S BASE LIGAND
AbstractThe complexes of Cu(II) and Ni(II) having the general composition ML2X2 (where L= 2-benzoylpyridine thiosemicarbazone, M=Ni(II),Cu(II), and X=Cl–, NO3–,SO42-, OAc–) have been synthesised and were characterised by IR, elemental analysis, magnetic susceptibility, UV-Vis, conductivity, mass spectrometry and EPR spectral studies. The IR spectral data indicates that the ligand behave as a bidentate ligand and coordinated to the metal ion through its nitrogen and sulphur donor atoms. The ligand is highly soluble in water. On the basis of molar conductance value which was determined by using DMSO as solvent it can be concluded that all the complexes were non electrolytic in nature. The value of magnetic moment indicates that all the complexes are of high spin type. On the basis of spectral studies an octahedral geometry has been proposed for Ni(II) complexes while tetragonal geometry was proposed for Cu(II) complexes.
