A complex of formula [MoO2(L)](acac)2 is obtained on treating molybdenyl acetylacetonate with di-2-thienylethanedione with 2,3-diaminotoluene This complex was reacted with four 1,3-diketones to yield four new complexes, [MoO2(ML)](acac)2, The complexes were characterized by elemental analysis, spectral studies and molar conductance. In these compounds, molybdenum exhibited a coordination number of six. Distorted octahedral environment surrounds molybdenum in these complexes. The ligand geometry was completed by two oxo O-atoms and four N-atoms. The synthesized complexes show moderate activity versus S. aureus and S. typhi.
Key words: Dioxomolybdenum(VI), di-2-thienylethanedione, 1,3-diketones, macrocyclic complexes, Schiff base.
