二(β—二酮)氧钒(Ⅳ)与含氮碱加合物的合成和表征

SYNTHESIS AND CHARACTERIZATION FOR ADDUCTS OF BIS (β-DIKETONATO) OXOVANADIUM(IV) WITH NITROGEN BASES

合成了一系列VO(β-dik)_2L类型加合物,其中β-dik分别为苯甲酰丙酮,2-噻吩甲酰三氟丙酮,L3-甲基吡啶、4-甲基吡啶、吗啉、异喹啉,VO(bza)_2Mor、VO(tta)_2Mor、VO(tta)_2iso-q为首次合成,并通过元素分析、摩尔电导、红外光谱、电子光谱、顺磁共振波谱等对加合物进行了较系统的表征工作。

A series of adducts of the type VO(β-dik)2L, where β-dik = benzoylacetonate anion(bza), thenoyltrifluoroacetonate anion(tta), L = pyridine (py), 3-methylpyridine(3MP), 4-methylpyridine(4MP), morpholine(Mor), iso-quinoline(iso-q), have been prepared, while VO(bza)2Mor, VO(tta)2Mor, VO(tta)2iso-q were first synthesized. All adducts were character-ized by elemental analysis, molar conductivity, IR,UV and ESRspetra.
