| Abstract: | A new series of four mixed-ligand complexes of oxoperoxomolybdenum(VI) of the general composition, [MoO(O₂)(2-hnd)(L)]H₂O, where 2-hndH = 2-hydroxy-1-naphthaldehyde and LH = o-acetoacetanisidide (o-aansH), o-acetoacetotoluidide (o-aatdH), acetylacetone (acacH) or methyl acetoacetate (macacH), has been synthesized by the interaction of [MoO(O₂)]²⁺ (in situ obtained during the interaction of MoO₃ and 30% H₂O₂ on continuous stirring at 50C for 24 h) and the ligands in aquous-ethanol medium. The complexes so obtained have been characterized by elemental analyses, molar conductance, decomposition temperature and magnetic measurements, thermogravimetric studies, ¹H-NMR, IR, mass and electronic spectral studies. Antibacterial studies of the ligand and the metal complexes have also been carried out. The complexes have been found to be more potent bactericides than the ligands. The 3D-molecular modeling and analysis for both bond lengths and bond angles have also been carried out for one of the representative compounds, [MoO(O₂)(2-hnd)(o-aatd)]H₂O (1), to substantiate the proposed structure. Pseudopentagonal bipyramidal structures have been proposed for these complexes. |
