Abstract

GRAPHICAL ABSTRACT: ABSTRACT: Dimethyl diphenyldithiophosphate complexes of Cr(III), [{(ArO)2 PS2 }3 Cr] [Ar = 2, 4-(CH3 )2 C6 H3 (1 ), 2, 5-(CH3 )2 C6 H3 (2 ), 3, 4-(CH3 )2 C6 H3 (3 ), and 3, 5-(CH3 )2 C6 H3 (4 )], have been synthesized and structurally characterized by IR, heteronuclear NMR ( 1 H, 13 C, and 31 P) spectroscopic and single crystal X-ray analyses. The crystal structure of complex4 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 (CrS2 P)3 heteroatomic ring and Cr(III) center. The ligands and complexes were evaluated for their antibacterial potential against six bacterial strains ( K. pneumoniae, E.coli, P. aeruginosa, B. subtilis, S. aureus, and S. typhimurium ). The metal derivatives of diphenyldithiophosphate ligands were found to be more active against the bacterial strains as compared to the free ligands.
