Synthesis and Spectroscopic Studies of 12-Membered Macrocyclic Transition Metal Complexes with Tetradentate Ligand

Abstract

Tetra-aza macrocyclic transition metals complexes of type: [M(C12H4N8)X2]; where, M = Co (II), Ni(II), Cu(II), Zn(II); X= Cl-1 , NO3 - , CH3COOhave been synthesized and characterized. On the basis of conductance data; elemental analyses, the character of the complexes have been suggest and it was found that all the complexes have 1:2:2 stoichiometry and are nonelectrolytic in nature. Tentative geometry of the new synthesized macrocyclic complexes had been proposed with the aid of variety of physicochemical studies like NMR, Infra-Red, ESR and Electronic spectra. Molecular modeling was also carried out for better understanding the structure of complexes. Based on various studies and molecular modeling, a distorted octahedral geometry has been proposed for metal complexes. All the synthesized metal complexes were screened for antimicrobial activities and show the comparable results with standard drugs.
