Synthesis And Characterization of New Mn(II), Co(II), Cd(II) and Hg(II) Complexes with ligand [N-(pyrimidin-2-ylcarbamothioyl)benzamide] and their Anti-bacterial Study

Abstract

Abstract A new ligand [N-(pyrimidin-2-ylcarbamothioyl)benzamide](L) has been synthesized through the reaction of the benzoyl iso-thiocyanate with a 2-Amino pyrimidine, The ligand had been identified by the elemental micro-analysis CHNS, UV-Vis, FT-IR, and 1 H, 13CNMR spectra, some of the transition metal complexes of that ligand have been produced and characterized with the use of the UVvis spectra, FT-IR, magnetic susceptibilities, conductivity measurements, and atomic absorptions. Ligand’s behavior is similar to bidentate coordinating via an S and O donor, From the results that have been obtained, molecular formula of all of the complexes that have been prepared have been [M(L)2Cl2] (M+2 =Mn, Cd, Hg and Co), the suggested geometrical structure for all of the complexes have been octahedral. The metal and ligand complexes exhibit good activities towards bacteria; Escherichia coli and Staphylococcus aureus.
