稀土配合物研究(Ⅻ)——1,6-双(1′-苯基-3′-甲基-5′-氧代吡唑-4′-基)己二酮-[1,6](BPMPHD)与稀土元素配合物的合成及表征

Studies on the Rare Earth Coordination Compounds(Ⅶ)——Synthesis and Characterization of Coordination Compounds of Rare Earth Element swith 1,6-Bis(1'-phenyl-3'-methyl 5' -pyrazolone-4' -)-1,6-hexanedione

我们曾研究过BPMPHD对稀土元素的萃取规律,三元配合物,以及在有机溶剂中形成的某些二元配合物的性质。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。

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.
