摘　　要：本文合成了稀土离子(Sm、Eu、Tb、Yb)与1-苯基-3-甲基-4-七氟丁酰基唑酮-5)及中性配体三苯基氧化膦、2,2—联吡啶、二甲基亚砜的三元固态配合物.研究了它们的组成、光谱和热稳定性质.发现这些配合物在常压下加热时表现出一定的挥发性质,其中以含配体三苯基氧化膦的配合物的挥发性为最好.The new solid complexes of rare earth ions(Sm,Eu,Tb,Yb),with 1-phenyl-3-methyl-4-heptaflurobutyryl-pyrazolone-5(PMHFP)and neutralligand triphenylphosphosphine oxide(TPPO)or 2′,2-bipyridine(Bipy) ordimethyl sulfoxide(DMSO)were synthesized in this paper.They werecharacterized by elemental analyses,infrared spectra,ultraviolet spectra,molar conductances,differentia thermal analyses(DTA)and thermogravimetry(TG).It was found in the study of the thermal stability that the complexes,especially in those containing ligand TPPO,showed the gasification property,that is,they can gasify in the form of the complex molecular when heatedto a certain temperature.
