SYNTHESIS, CHARACTERIZATION AND ANTIFUNGAL, ANTIBACTERIAL STUDIES OF HYDRAZONE-OXIME METAL COMP.....

H2L (C13H18N4O2), a novel oxime ligand, was produced via condensation of alcoholic solutions of hydrazide molecule and acetyl monoxime. [(HL)Co2(OAc)2(H2O)4], [(HL)Mn(OAc)(H2O)], [(HL)Zn(OAc)(H2O)], [(HL)Ni(OAc)(H2O)], [(HL)RuCl2(H2O)], [(HL)Fe2Cl4(H2O)3], and [(H2L)2UO2(NO3)2] The complexes were isolated in solid form and characterised by elemental analysis (C, H, N), magnetic susceptibility studies, spectrum (UV-Visible, IR, 1H and 13C NMR), thermal analysis, and molar conductivity. A preliminary structure for these complexes was hypothesised and suggested, with coordination numbers of six around Co(II), Mn(II), Zn(II), Ni(II), Ru(III), and Fe(III) metal ions, and eight around UO2(II) ion. Elemental analysis, stoichiometric data, and spectroscopic data of metal complexes revealed that the metal: Ligand ratio of Co(II) and Fe(III) complexes was 2M:1L, but it was 1:1 in Mn(II), Zn(II), Ni(II), and Ru(III) complexes and 1:2 in UO2(II) complexes. Finally, the bioactivity of the ligand and its complexes was evaluated.
