2，6－双（1′－苯基－3′－甲基－5′－氧代－4′－甲酰吡唑）吡啶稀土配合物的合成与表征

Synthesis and Characterization of 2, 6-Bis-(1′-phenyl-3′-Methyl-5′-Oxo-4′-Formylpyrazol)Pyridine and Its Rare Earth Complexes

在乙醇－水溶液中合成了１４种２，６－双（１′－苯基－３′－甲基－５＇－氧代－４＇－甲酰吡唑）吡啶稀土配合物。元素分析确定其化学组成为ＲＥ＿２Ｌ＿３·ｎＨ＿２Ｏ，并用紫外可见光谱、红外光谱、核磁共振谱、热分析、荧光光谱、摩尔电导等进行了表征。

A novel ligand 2,6-bis (1′- phenyl-3′-methyl-5'- oxo-4'-formylpyrazol)pyridine(H2L)and its complexes have been prepared by reacting H2L with rare earth nitrate in ethyl alcohol solution. The complexes have been characterized by elemental analysis,thermoanal-ysis,molar conductivity,IR,UV,1H NMR and fluorescence spectra measurements.
