Preparation of new macrocyclic ligand and characterization complexes of some transition metals

الملخص EN

The 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.
