摘要: Six mononuclear Mo(V) Schiff-base complexes were prepared by the reaction of MoCl5 with Schiff bases, namely HL1–HL3 and HL4–HL6, such as 5-hydroxy-3-methyl-1(2-chloro)phenyl-1H-pyrazolone-4-carbaldehyde (I), 5-hydroxy-3-methyl-1(3-chloro)phenyl-1H-pyrazolone-4-carbaldehyde (II), 5-hydroxy-3-methyl-1(3-sulfoamido)phenyl-1H-pyrazolone-4-carbaldehyde (III) ethanolamine propanolamine, respectively, in aqueous ethanolic medium. The resulting have been characterized elemental analyses, molar conductance, FT-IR, 1H-NMR, electronic, electron spin resonance (ESR) spectra, magnetic susceptibility, thermal study. conductivity data show them to be non-electrolytes. IR 1H-NMR spectral suggest that ligand is a dibasic bidentate ON donor toward metal ion. Electronic, magnetic, ESR oxomolybdenum(V) distorted octahedral geometry. One chloride coordinated molybdenum confirmed
