It has been reported that molybdenum may extract oxygen from oxygen containing ligands. Oxo complexes of above bases with transition metals show numerous applications and are biologically active. So to study the biological activity of molybdenum complexes and to study oxo abstraction reactions by molybdenum, reactions of succinimide/1, 4-diaminobutane/3-methylpyridine/1, 3-diaminopropane/pyrazole/1-methylpyrrolidine with MoCl5/MoO2Cl2 have been carried out, in THF medium using equimolar/bimolar quantities of the ligand, at normal temperature. The products thus obtained are: Mo2O3Cl5(C4H5NO2)2(C4H8O)2, [1]; Mo2O2Cl2(C4H5NO2)2(C4H8O)2, [2]; MoO2Cl2(H2NCH2CH2CH2CH2NH2)2, [3]; Mo3Cl8(C6H7N)4(C4H8O)2, [4]; Mo3Cl6(C6H7N)6(C4H8O)6, [5]; MoO2Cl3(H2NCH2CH2CH2NH2)2, [6]; Mo2O4Cl4(C3H4N2)4, [7] and Mo2O6Cl8(C5H11N)4, [8]. There is oxygen abstraction by molybdenum during the reaction from the oxygen containing solvent THF. Formulations of these compounds were made and their properties were studied with FTIR(transmission mode), 1H NMR/13C NMR, microbiological studies, elemental analysis(Mo, Cl, C, H, N) and LC-MS. All preparations, separations and isolations were executed in vacuum line and inert atmosphere (dry nitrogen) to eliminate any oxidation/hydrolysis of products by air/moisture. The formulations proposed have been supported by the above characterization studies.

MoCl5 reactions with 4-methylpyridine/2-methylpyridine/1-methylimidazole in THF in 1:1/1:2 stoichiometric ratios, at room temperature were carried out. The following products were synthesized: MoO2Cl(C6H7N), 1;Mo2O2Cl5(C6H7N)2(C4H8O)2,2; Mo4O4Cl4(C6H7N)3(C4H8O)2, 3 and Mo2O4Cl4(C4H6N)2(C4H8O), 4. These compounds have been investigated by FT-IR (transmission mode), FT-1H NMR, FT -13C NMR, microbiological, LC-MS and elemental (C, H, N, Mo, Cl) studies. In view of the sensitivity of all the reactants and products towards oxidation/hydrolysis by air/moisture, all the reactions and products were handled using dry nitrogen atmosphere in vacuum line. LC-MS and elemental studies agree with the formulae of compounds.

MoOCl4/MoO2Cl2 were reacted with 2-mercaptopyridine (IUPAC: pyridine-2-thiol)/4-phenylimidazole-2-thiol (IUPAC: 4-phenyl-1, 3-dihydroimidazole-2-thione)/6-mercaptopurine (IUPAC: 1, 7-dihydro-purine-6-thione) in acetonitrile medium using equal/twice molar concentrations at normal temperature. The reactions yielded products: MoOCl3(C5H4NS-SNH4C5).2HCl, [1]; Mo3O3Cl12(C5H4NS-SNH4C5)(CH3CN)2, [2]; Mo2OCl6(C9H7N2S)4, [3] and Mo2O2Cl8(C5H4N4S)(CH3CN), [4]. The various techniques used for characterization of compounds are: Fourier transform infrared, proton nuclear magnetic resonance, 13C nuclear magnetic resonance, liquid/gas chromatography mass spectrometry and C, H, N, S, Mo, Cl analysis. The products are prone to oxidation/hydrolysis by air/moisture, so all procedures were executed in vacuum line using dry nitrogen atmosphere. Elemental analysis and fragments recorded in mass spectrometry are in tune with the formulae proposed.
