Abstract

Abstract

Microwave and traditional methods were used to synthesis a novel derivative of the thiourea ligand N-(p-methylphenyl)-N'-Benzoyl thiourea (MBT) and its transition metal complexes of Co (II), Ni (II), Cu (II), and Zn (II). Elemental analysis, FT-IR, mass spectroscopy, 1HNMR, 13CNMR, and UV-Visible were used to investigate the structure of MBT ligand and their complexes. Geometry of proposed chelate complexes was studied using electronic spectra, electron spin resonance (ESR), and magnetic susceptibility. Thermal gravimetric analysis (TGA) was used to study the solidity of complexes. X- ray diffraction XRD was used to investigate the surface morphologies of solid complexes. Antimicrobial activity of MBT ligand and their complexes was investigated. Also proposed chelate complexes were examined in vitro by radical scavenging activity (DPPH) to evaluate their antioxidant activity. The anticorrosion activity of the ligand was studied by weight loss method
