Synthesis, characterization anti antibacterial activity of binuclear complexes of chiral Schiff base 2,6-bis (1S, 2R-2-hydroxy-1-methyl 2-phenylethylimino)-4-heptanone

Binuclear complexes of VO(IV), Cr(II), Co(II), end Cu(II) with the title li gand were synthesized and characterized by elemental analysis and infrared spectra. The metal ions occupy the ONONO coordination sites of the ligand w hile acetates and two H2O molecules associated with each complex to satisfy the coordination requirements of the metal ions. The binuclear complexes h ave comparatively higher antibacterial activity as compared to their mononu clear analogs.
