Preparation of New Macrocyclic ligand and Characterization complexes of Some Transition metals

Abstract

AbstractThe chelate complexes of Ni (II),Cu(II) and Zn(II) with new Schiff base derived from 4-aminoantipyrine,4-dimethylaminobanzaldehyde,p-hydroxylbanzaldehyde and ethylene diamine are prepared and characterized through elemental analyses,IR,electronic spectra, magnetic moment, and molar conductance measurement . The molar conductance data revel that all the metal chelates of the ligand with Ni (II) , Cu (II) and Zn (II) are electrolytes . The coordinating ligand act as neutral tetra dentate manner , with N4 doner sites of azo methine (C=N). The central metal ion displays the coordination number 4 in these complexes .Key words : Schiff base ,Anti pyrine , Metal chalet complexes, Characterization.
