三元配合物UO_2(PhenNO)(acac)_2·H_2O的合成与性质

SYNTHESIS AND CHARACTERIZATION OF TERNARY COMPLEX OF UO_2(PhenNO)(acac)_2 ·H_2 O

摘要: <正> 邻菲啰啉单氮氧化物(PhenNO)与f过渡元素能形成稳定的配合物,但以PhenNO为配体的混配配合物的性质至今未见报道。β-二酮类作为较好的螯合萃取剂与各种中性萃取剂在协同萃取锕系元素方面已有研究应用。我们首次合成了PhenNO及乙酰丙酮(Hacac)与铀酰的三元配合物,并对其组成和有关性质进行了研究。

Abstract: The ternary coordination compound of UO2(PhenNO)(acac)2·H2O(PhenNO = 1,10-phenanthroline-N-oxide; acac = acetylacetonate anion) is prepared for the first time. The physical and chemical properties of the new compound are studied with elemental analyses, IR spectrum, UV spectrum, TG-DSC, molar conductance and solubility.
