Synthesis, Characterization and Antibacterial Activity of Binuclear Complexes of Chiral Schiff Base 2,6-Bis (1S, 2R-2-Hydroxy-l-Methyl 2- Ph enylethylim in o)-4-Heptanone

Abstract

Binuclear complexes of VO(IV), Cr(1I), Co(II), and Cu(lI) with the title ligand were synthesized and characterized by elemental analysis and infrared spectra. The metal ions occupy the ONONO coordination sites of the ligand while acetates and two H2O molecules lire associated with each complex to satisfy the coordination requirements of the metal ions. The binuclear complexes have comparatively higher antibacterial activity as compared to their mononuclear analogs.
