摘要: 我们曾研究过BPMPHD对稀土元素的萃取规律[1],三元配合物[2],以及在有机溶剂中形成的某些二元配合物[3]的性质。发现,由于BPMPHD是1种具有4个配位原子的螯型配合剂,它与稀土元素可以形成不同组成的配合物,对研究稀土新型配合物,探索金属间能量传递、光化学活性、催化性能均有重要意义,这类工作将会引起更多化学工作者的兴趣。

Abstract: Fourteen solid coordination compounds of title compound(BPMPHD) with rare earths were synthesized from aqueous ethonal solution. Elemental analysis agree with proposed stoichiometric RE2A3.4H2O (where RE = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb. A = C26H24N4O42-). The compounds were characterized by UV, IR, molar conductance, fluorescence spectra and thermoanalysis. The dinuclear structures of these complexes were confirmed by X-ray powder diffraction.

Key words: Rare earth elements, 1, 6-Bis(1'-phenyl-3'-methyl-5' -pyrazolone- 4' )-1, 6-Hexanedione, Coordination compound
