Molybdenum is a versatile transition metal and a number of chemical reaction as well as physiological reactions are catalysed by its complexes. Its most important oxidation state is +6 in which it exists in the form of dipositive dioxo molybdyl cation MoO22+ We intent to synthesize some Molybdenum complexes through condensation between Dioxo(2,4-pentanedionato) molybdenum(VI) and sulfapyridine with 2-acetylnaphthalene, 2-acetylthiophene, thiophene-2-carbaldehyde. The ligands thiophene thiosemicarbazone (LH) was prepared by the condensation of thiophene-2-carbaldehyde and thiosemicarbazone and other was prepared by the condensation of different sulfadrugs with various aldehydes and ketones. The synthesized Molybdenum complexes and ligands have been characterized by various spectral as IR, NMR, UV, X-Ray Spectral and elemental analysis. Higher biological activity due to their ability to chelate trace with metals and enables their application as antitumor, antifungal, antibacterial, and antitubercular drugs. The complexes are monomeric and diamagnetic octahedral structure. Within the second series of transition metals only molybdenum increasing biological application, namely antibacterial, antifungal, antitubercular, anti-tumour, activities etc, of the complexes of transition metals. The increased potency of metal complexes may be assigned to their increased lipophilic nature due to their chelation. These Mo sites supposed to be active centres for the catalytic activity of the enzymes. Mo is one of the most biologically active elements is an essential micronutrients for microorganisms, plants and animals. There is extensive literature on the use of Dioxomolybdenum (VI) complexes as catalysts in some important industrial processes, as well as their role in some biological processes
