The interaction of bis(acetylacetonato)oxovanadium(IV), [VO(acac)2] with biomimetic hydrazone ONO donor ligands HL in 1:1 mole ratio [where, HL = N-(4′-benzoylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one)-isonicotinic acid hydrazide (bmphp-inH, I), N-(4′-butyrylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one)-isonicotinic acid hydrazide (bumphp-inH, II), N-(4′-acetylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one)-isonicotinic acid hydrazide (amphp-inH, III), N-(3′-methyl-1′-phenyl-4′-propionylidene-2′-pyrazolin-5′-one)-isonicotinic acid hydrazide (mphpp-inH, IV) and N-(4′-iso-butyrylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one)-isonicotinic acid hydrazide (iso-bumphp-inH, V)] in a mixed solvent (ethanol-methanol, 1:10) via aerial oxidation for 2-3 days yield dioxovanadium(V) complexes of composition [VO2(L)(H2O)] · H2O. The compounds so obtained were characterized on the basis of elemental analyses, thermogravimetry, vanadium determination, IR, Electronic, 51V NMR, 1H NMR and mass spectral studies. The 3D molecular modeling and analysis for bond lengths and bond angles have also been carried out for one of the representative compounds, [VO2(ampph-in)(H2O)] (3).
Metal nitrosyl complexes of bioinorganic, catalytic, and environmental relevance: A novel single-step synthesis of dinitrosylmolybdenum(0) complexes of {Mo(NO)2}6 electron configuration involving Schiff bases derived from 4-acyl-3-methyl-1-phenyl-2-pyrazolin-5-one and 4-aminoantipyrine, directly from molybdate(VI) and their characterization

This paper reports the synthesis of five new hexa-coordinated mixed-ligand dinitrosyl complexes of molybdenum(0) of the composition [Mo(NO)2(L)(OH)], where LH = N-(3′-methyl-1′-phenyl-4′-valerylidene-2′-pyrazolin-5′-one)-4-aminoantipyrine (mphvp-aapH), N-(4′-benzoylidene-3′-methyl-1′-phenyl-2 ′-pyrazolin-5′-one)-4-aminoantipyrine (bmphp-aapH), N-(3′-methyl-1′-phenyl-4′-propionylidene-2′-pyrazolin-5′-one)-4-aminoantipyrine (mphpp-aapH), N-(4′-acetylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5 ′-one)-4-aminoantipyrine (amphp-aapH) or N-(-4′-iso-butyrylidene-3′-methyl-1′-phenyl-2′-pyrazolin-5′-one)-4-aminoantipyrine (iso-bumphp-aapH) directly from molybdate (VI) in a single step and in a single pot. The compounds so obtained have been characterized by elemental analyses, molar conductance, decomposition temperature and magnetic measurements, thermogravimetric analyses, infrared and electronic spectral studies. They were found to contain low-spin [Mo(NO)2]6 electron configuration. A cis-octahedral structure has been proposed for these complexes. The 3D molecular modeling and analysis for bond lengths and bond angles have also been carried out for one of the representative compounds, [Mo(NO)2(bmphp-aap)(OH)] (2).
