Synthesis of several novel dioxomolybdenum(VI) complexes with formula [MoO2(mac)](acac)2, (where mac = tetraazamacrocyclic ligands derived from condensation of thenil with 1,2-diaminobenzene or 2,3-diaminopyridine and their reactions with β-diketones), using dioxometal ion as kinetic template are reported. The complexes were characterized by molar conductance, elemental analyses, infrared and UV-Vis spectral studies. The spectral data indicate that ligands act as tetradentate chelating agent.

The antibacterial activities of the synthesized complexes were tested against six different bacterial strains. Almost all the complexes showed low to moderate activity against Staphylococcus aureus, Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa. Abstract Keywords: dioxomolybdenum(VI), thenil, macrocyclic complexes.
