Synthesis, Structure and Characterization of Novel Acylselenourea Ligand and its Complexes; Antibacterial Activity and Thermal Analysis

Abstract

Synthesis of Novel of ligand (E)-N-(2-benzylidenehydrazine-1-carbonoselenoyl) benzamide with three of mononuclear metals complexes. The acyl chloride in mixture of Potassium selenocyanate and hydrazine hydrate for formation precursor N-(hydrazinecarbonoselenoyl) benzamide that reacted with benzaldehyde, subsequently novel ligand was synthesis. The H2L reaction with Cu (II), Zn (II), and Cd (II), ions have commanded to separation of novel of complexes with overall formula K[MLCl], (M=Cu (II), Zn (II) and Cd(II). The synthesized of Acylselenourea-compounds have been characterized by C, H and N analysis, FT-IR, UV-Visible, 1H- and 13C-, and Se-NMR, as well as Mass spectra, effective magnetic moments, molar conductance, and TG-DSC. The separation of square planer geometry around (Cu (II) and tetra-hedral geometry around Zn (II) and Cd (II) ions has been seen in analytical and spectroscopic investigations of complexes. The ligand of H2L and also its metal complexes have been discovered to be antibacterial against Gram (-) bacterium types such as Escherichia coli, Klebsiella pneumoniae, and Bacillus sabtuius., in addition to, metal complexes could have a better level of resistance to microbial activity than free ligand, according to strains of the Gram (+) bacterium Staphylococcus aureus.
