在水热条件下合成配合物[Eu(HCAM)3]·[(H2O)2(4,4’-bipy)2]单晶(HCAM为4-羟基-2,6-吡啶二羧酸,4,4’-bipy为4,4’-联吡啶).通过元素分析,红外光谱和X-射线单晶衍射法测定配合物的结构,该晶体属于三斜晶系,P-1空间群,在晶体结构中含有2个独立4,4’-联吡啶配体,中心Eu(Ⅲ)离子是九配位的配位构型.荧光性质测试表明:具有稀土离子基本荧光特征,主要发射峰位于617 nm,体现出红光特征.
The complex of [Eu (HCAM) 3] · [(H2O) 2 (4,4’-bipy) 2] was synthesized under hydrothermal conditions (HCAM is 4-hydroxy-2,6-pyridinedicarboxylic acid, , 4’-bipy is 4,4’-dipyridyl) .The structure of the complex was determined by elemental analysis, IR and X-ray single crystal diffraction, belonging to the triclinic, P-1 space group, The crystal structure contains two independent 4,4’-dipyridyl ligands, and the central Eu (Ⅲ) ion is a nine-coordinated complex. The fluorescence properties show that the Eu (Ⅲ) ion possesses the basic fluorescence characteristics of rare earth ions with the main emission peak at 617 nm, reflecting the red features.
