Synthesis, characterization and antibacterial study of cyclometalated rhodium(III) complex containing dithiocarbamate
Abstract The novel cyclometalated Rh(III) complex, [Rh(phpy)2(S^S) Where phpy is 2 phenylpyridine and (S^S) is diethyldithiocarbamate, has been prepared and characterized by elemental analysis, IR, 13C and 1H NMR, electronic absorption and Fluorescence spectroscopies, cyclic voltammetry, and X ray crystallography. The crystal structure of [Rh(phpy)2(S^S) shows that the coordination geometry around the Rh(III) is a distorted octahedron, with bite angles of 71.19 81.04deg for all three bidentate ligands. Electrochemical analysis by cyclic voltammetry reveals irreversible redox behavior of the rhodium centre. Antibacterial activity of the complex has also been studied by agar disc diffusion method against three Gram negative bacteria (Pseudomonas aeroginosa, Salmonella typhi and Escherichia coli) and two Gram positive bacteria (Staphylococcus aureus and Corynebacterium renale)
