摘要： 自从1959年Jensen[1]将1-苯基-3-甲基-4-苯甲酰基-吡唑酮-5(HPMBP)推荐为一种新型β-二酮类萃取剂以来,用它作为酸性螯合配体而合成的稀土三元配合物为数不少,但所涉及的中性配体多为膦氧单齿配体[2~5]和以氮为配位原子的联吡啶及二氮杂菲类双齿配体。α-亚硝基-β-萘酚(NN)作为酸性配体已被广泛地用于过渡元素的溶剂萃取,但用它作为中性配体的稀土三元配合物尚未见报道。本文报道了14种稀土离子与HPMBP及NN的二元固态配合物的合成并对其红外光谱、质子核磁共振谱进行了研究。

Abstract: This paper reports the preparation and properties of the complexes of rare earths with 1-phenyl- 3-metlfyl-4-benz6yl-pyrazolone-5 (HPMBP) and 1-nitroso-2-naphthol (NN).Compounds of general formulas RE(PMBP)3(NN) (whereRE=La, Pr,Nd,Sm,Lu and Y)were obtained and characterized by elemental ana-lysis,IRspectra and 1H NMR.All fourteen-complexes obtained are gray-violet crystal. They are soluble in ethanol, acetone and benzene, but insoluble in water. In atmosphere, these complexes are stable at room temperture.

Key words: 1-Phenyl-3-methyl-4-benzoyl-pyrazolone-5, 1-Nitroso-2-naphthol
