The crystal structure of complex <b>4</b> reveals mononuclear units with the Cr(III) centre chelated in bidentate fashion by six S atoms of the three diphenyldithiophosphate ligands to form octahedral geometry. The main core of the system comprised of four membered (CrS<sub>2</sub>P)<sub>3</sub> heteroatomic ring and Cr(III) center. The ligands and complexes were evaluated for their antibacterial potential against six bacterial strains (<i>K. pneumoniae, E.coli, P. aeruginosa, B. subtilis, S. aureus</i>, and <i>S. typhimurium</i>). The metal derivatives of diphenyldithiophosphate ligands were found to be more active against the bacterial strains as compared to the free ligands.</p>
