合成了14种稀土元素与1,4—双(1′—苯基—3′—甲基—5′—氧代吡唑—4′—基)丁二酮—〔1,4〕(BPMPBD)和2,2′—联吡啶(BiPy)的配合物。配合物组成为:Ln_2(BPMPBD)_3(BiPy)_2·nH_2O和Ln_2(BPMPBD)_3BiPy·nH_2O。研究了配合物的摩尔电导、红外光谱、核磁共振谱、荧光光谱和差热—热重谱。认为BPMPBD为二价四齿配体,配合物具有双核结构。
14 kinds of rare earth elements and 1,4-bis (1’-phenyl-3’-methyl-5’-oxopyrazole-4’- And 2,2’-bipyridine (BiPy). The complexes consist of Ln_2 (BPMPBD) _3 (BiPy) _2 · nH_2O and Ln_2 (BPMPBD) _3BiPy · nH_2O. The molar conductance, infrared spectra, nuclear magnetic resonance spectra, fluorescence spectra and TG-TG spectra of the complexes were studied. It is considered that BPMPBD is a bivalent tetradentate ligand and the complex has a dual-core structure.
