Synthesis and Characterization of [1-phenyl-3-naphthoyl-2-thiourea] and Its Metal Complexes with [Co (II), Ni (II), Cu (II), Zn (II), and Cd (II)] ions and Study Antibacterial Activity and Corrosion Inhibitor

Basim Ibrahim Al-Abdaly


The formation of Co (II), Ni (II), Cu (II), Zn (II) and Cd (II)-complexes (C1-C5) respectively were studies with new thiourea ligand [1-phenyl-3-naphthoyl-2-thiourea] from 2-naphthoic acid in three steps. The suggested structures of the ligand and its complexes have been determined   by using C.H.N.S analyzer, thermal analysis, FT-IR, U.V-Visible, 1HNMR, 13CNMR, conductivity measurement, magnetic susceptibility, and atomic absorption. According to these studies, the ligand coordinates as  a bidentate with metal ions through  oxygen atom of  carbonyl, and  sulfur atom of thione  and the ratio of  metal to ligand (M:L) as (1:2) and all the complexes were octahedral structures except copper-complex was distorted octahedral structure

Keywords: Thiourea ligand, antibacterial activity, Corrosion inhibitor.
