A novel dioxidomolybdenum complex, [MoO(2)L], derived from the tridentate aroylhydrazone 2-amino-N'-(2-hydroxy-3-methylbenzylidene)benzohydrazide (H(2)L), has been prepared and characterized by elemental analysis, FT-IR, (1)H NMR, and single crystal structural X-ray diffraction. The complex has distorted square pyramidal structure in which the aroylhydrazone ligand behaves as a binegative donor...
