Studies on Synthesis and Characterization of the Ternary Complexes of Europium(Ⅲ)-β-diketonate-4,4'-bipyridine-N,N'-dioxide

Abstract

Abstract: 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'-bipyN₂O₂) by elementary analysis,Their properties were studied with IRabsorption and fluorescence spectroscopies.Their possible structures are also proposed.

Key words: Europium(Ⅲ), 4,4'-Bipyridine-N,N'-dioxide, β-Diketone, Ternary complex
