摘要：
The present paper reports the synthesis and characterization of two series of vanadium compounds: (a) oxovanadium(IV) complexes of the composition, [VO(L-1)(L-2)(H2O)] {L1H = 4-benzoyl-3-methyl-1-phenyl-2-pyrazoline-5-one (bmpph), L2H = acetoacetanilide (aaH), o-acetoacetotoluidide (o-aatdH), o-acetoacetanisidide (o-aansH), methylacetoacetate (macacH), ethylacetoacetate (eacacH) or dibenzoylmethane (dbmH), and (b) dioxovanadium(V) complexes with Schiff bases (aroylhydrazones) of the composition, [VO2(L)(H2O)]center dot H2O (LH = Schiff base derived from isonicotinic acid hydrazide (inH) and bmpph, 4-butyryl-3-methyl-l-phenyl-2-pyrazolin-5-one (bumpph), 4-acetyl-3-methyl-l-phenyl-2-pyrazolin-5-one (ampph), 3-methyl-l-phenyl-4-propionyl-2-pyrazolin-5-one (pmpph) or 4-iso-butyryl-3-methyl-l-phenyl-2-pyrazolin-5-one (iso-bumpph). The 3D-molecular modeling and analysis for bond lengths and bond angles have also been carried out for one representative compound of each series. (c) 2006 Elsevier Ltd. All rights reserved.
