Thaker, B. T. published the artcileSynthesis, spectral, and thermal studies of oxomolybdenum(V) Schiff-base complexes derived from heterocyclic β-diketone, Recommanded Product: 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is Journal of Coordination Chemistry (2010), 63(9), 1597-1610, database is CAplus.
Six mononuclear Mo(V) Schiff-base complexes were prepared by the reaction of MoCl5 with Schiff bases, namely HL1-HL3 and HL4-HL6, formed from the reaction of 3-methyl-1-(2-chloro)phenyl-1H-pyrazol-5-one-4-carbaldehyde (I), 3-methyl-1-(3-chloro)phenyl-1H-pyrazol-5-one-4-carbaldehyde (II), and 3-methyl-1-(3-sulfonamido)phenyl-1H-pyrazol-5-one-4-carbaldehyde (III) with ethanolamine and propanolamine, resp., in aqueous ethanolic medium. The resulting complexes were characterized by elemental analyses, molar conductance, FTIR, 1H NMR, electronic, ESR spectra, magnetic susceptibility, and thermal study. The molar conductivity data show them to be non-electrolytes. IR and 1H NMR spectral data suggest that the ligand is a dibasic bidentate with ON donor toward metal ion. Electronic, magnetic, and ESR spectral data suggest that the oxomolybdenum(V) complexes have distorted octahedral geometry. One chloride coordinated to molybdenum is confirmed by thermal study.
