Abstract

Certain metal complexes exhibit different characteristic properties depending on the nature of the metal as well as the type of ligand. The complexes of Mn(II), Co(II), Ni(II), Cr(III), Cu(II), Zn(II) and Cd(II) with the chelating ligand derived from 1-(2,4-dihydroxyphenyl) ethanone and 2-chloropyridine-3-carboxamide have been synthesized. The chelates have been characterized on the basis of elemental analyses, IR, 1HNMR, diffuse reflectance spectral and magnetic moment studies. The complexes are found to be colored and stable in air at room temperature. The structure of the ligands were elucidated by spectral studies which indicate the presence of two or three coordinating groups in ligands which may be oxygen atom of the phenolic -OH group, the nitrogen atom of the azomethine (C=N) group and the oxygen atom of the carbonyl group.
