Dinitrosylmolybdenum(0) complexes of catalytic and environmental relevance: A novel single step synthesis of dinitrosylmolybdenum(0) complexes of {Mo(NO)₂}^6* electron configuration involving biologically active 8-roxyquinolinesulphonamides directly from molybdate(VI) and their characterization

Abstract

Six hexacoordinated mixed-ligand dinitrosyl complexes of molybdenum(0) of composition, [Mo(NO)₂(L-L)₂]×H₂O {where (L-L)H = 8-hydroxyquinoline-4-(<i>o</i>-tolyl)-sulphonamide (HQOTS,I), 8-hydroxyquinoline-4-(<i>m</i>-tolyl)-sulphonamide (HQMTS, II), 8- hydroxyaquinol ine-4-(<i>o</i>-methoxyphenyl)sulphon amide (HQOMPS, III), 8-hydroxyquinoline-4-(<i>m</i>-methoxyphenyl) sulphonamide (HQMMPS, IV), 8-hydroxyquinoline-4-(<i>o</i>-ethoxyphenyl)-

sulphonamide (HQOEPS, V) and 8-hydroxyquinoline-4- (<i>m</i>-ethoxyphenyl)sulphonami de(HQMEPS,VI)}, have been synthesized in a single step directly from molybdate(VI). The complexes so obtained have been characterized by elemental analyses, molar conductances,

decomposition temperatures, magnetic measurements,¹H-NMR, infrared and electronic spectral studies. All the complexes are found to contain low-spin {Mo(NO)₂}⁶ electron configuration.
