摘　　要：铕（Ⅲ）－β－二酮－４，４＇－联吡啶－Ｎ，Ｎ＇－二氧化物三元配合物的合成与表征林惠文，朱文祥（海南师范学院化学系，海口，５７１１５８）（北京师范大学化学系，北京，１００８７５）关键词铕（Ⅲ），４，４＇－联吡啶－Ｎ，Ｎ＇－二氧化物，β－二酮，三元配合物...A new ligand 4,4'-bipyridine-N,N'-dioxide and two europium (Ⅲ) ternary complexes of β-diketonate and 4,4'-bipyridine-N,N'-dioxide were first prepared[the β-diketonates are thenoyltrifluoracetonate(TTA-) and dibenzoylmethanate(DBM-)].Their compositions were determined as formulae of Eu(TTA)3·0.5L and Eu(DBM)3·0.5L(L=4, 4'-bipyN2O3) by elementary analysis,Their properties were studied with IR absorption and fluorescence spectroscopies.Their possible structures are also proposed.
