Template Synthesis and Characterization of 16-Membered Octaazamacrocycliccu (II) Complexes
Author Name : Rajeev Kumar Singh
ABSTRACT: Cu(II) complexes with a distorted Octahedral nitrogen donor octaazamacrocyclic ligand was synthesized. The formula of the complex was derived on the basis of elemental analysis. It was found to be of the type [Cu(L)X2] (L=16-membered Octaaza macrocyclic ligand obtained by the metal ion catalysed template Schiff base condensation of diacetyl with hydrazine. Molar conductance data (12 S cm2 mol-1) indicate the complex to be non-electrolytic in nature. Magnetic moment data for the complex was found to be 1.98 B.M. Electronic spectral studies reveal distorted octahedral stereochemistry for the copper complex. Infrared spectra suggest co-ordination to take place with nitrogen donor atoms. Axial coordination is satisfied with chlorine/acetateions.
