Synthesis and Characterization of Sodium Diphenylcarbamodithioate Ligand [L] and its Cobalt, Nickel, and Copper Complexes

Abstract

Abstract-A correlation of the infrared (IR) spectra of thiocarbonyl derivatives based on the literature data has been carried out. Assignments have also been made in some new systems. Sodium diphenylcarbamodithioate ligand and its monomeric complexes were synthesized at room temperature and stirring condition. The ligand and its complexes of the general formula [M(L) 2 ] (where M=Co п , Ni п , and Cu п ) were characterized by spectroscopic methods (IR and ultraviolet-visible), elemental analysis (CHN and S) metal content, magnetic susceptibility measurement, and biological activity (an antibacterial activity of the complex was studied by agar disc diffusion method and minimum inhibitory concentration strain against Staphylococcus aureus and Bacillus subtilis). The complex exhibited significant activities against S. aureus and B. subtilis, thin-layer chromatography, mass spectrometry, X-ray powder diffraction, and molar conductance. Our study revealed the formation of four-coordinate square planar complexes around Co п , Ni п , and Cu п metal ions.

“…The [Pd 2 LCl 4 ] complex have bands at 23474, 28571 and 40322 cm -1 which were attributed to 1 A 1 g to 1 B 1 g, 1 A 1 g to 1Eg, and charge transfer transition respectively (Howlader, et al, 2019). The [Pt 2 LCl 4 ] complex shows bands at 22988, 32467 and 39062 cm -1 , the first one peak was referred to 1 A 1 g→ 1 B 1 g and the other two peaks which were indicated C.T transition (Alsalihi, et al, 2017).…”

“…Concentrations of zinc ions are necessary for optimal bacterial growth of most in vitro microorganisms. However, high concentrations of zinc ions may show some antimicrobial activity against various bacterial and fungal strains [11]. As soon as, zinc is used as nonbactericidal and at specific concentrations can block or hinder the biofilm formation by several Gram-positive or Gram-negative bacterial swine pathogens [12].…”
