Synthesis of Bivalent Ni(II), Cu(II) and Zn(II) Complexes of Azodicarbonamide in Mixture of Methanol and Aqueous Solvents: Spectral Characterizations and Anti-Microbial Studies

Three new transition-metal complexes were produced by refluxing azodicarbonamide (ADCA) with nickel(II), copper(II), and zinc(II) solutions in a mixture of 50% (v/v) methanol water. The magnitude chelation between metal ions ligand molecules was assessed FT-IR, UV, elemental analysis, TGA, conductivity, mass, magnetic susceptibility measurements. FT-IR analysis suggested bi-dentate all complexes, which takes place through the N-azo O-carbonyl groups. Based on measurement moments spectral distorted octahedral geometry proposed for Ni(II) Cu(II) whereas zinc complex showed hexa-coordinated geometry. optical band gaps copper(II) found to be 1.91, 2.50, 1.96 eV, respectively, means that they can employed as semiconductors are same range highly effective photovoltaic materials. Urbach energy parameters also estimated from other parameters. biological activity its synthesized has been screened against selected gram bacteria (+ve) fungi.
