| 摘 要： | 采用模板法合成了2个异双核三价稀土席夫碱配合物: {Ce1.5Sm0.5(clapi)]2}·2CH3CN(1)和{La1.5Sm0.5(clapi)]2}·2CH3CN(2). 通过元素分析和红外光谱对这两个配合物进行了表征. 测定了配合物1的晶体结构, 结果表明配合物1属于三斜晶系, P1空间群. 晶胞参数: a=1.067056(2) nm, b=1.14700(3) nm, c=1.38734(3) nm, α=109.4240(10)°, β=98.0520(10)°, γ=105.8050(10)°, Z=1, Dc=1.650 Mg/m3, F(000)=740, R1=0.0582, wR2=0.1184I>2σ(I)]. 研究了配合物1和2在CH2Cl2中的室温荧光性质, 2个配合物都显示了Sm3+较弱的红色荧光, 研究结果证明荧光惰性稀土离子能够影响稀土配合物的荧光性质.

| Abstract: | Two hetero-dinuclear lanthanide(Ⅲ)/Schiff-base complexes {Ce1.5Sm0.5(clapi)]2}·2CH3CN(1) and {La1.5Sm0.5(clapi)]2}·2CH3CN(2) were synthesized using template method and characterized by elemental analysis and IR spectra. The structure of complex 1 was determined. Unit cell parameter of complex 1: a=1.067056(2) nm, b=1.14700(3) nm, c=1.38734(3) nm, Z=1, Dc=1.650 Mg/m3, F(000)=740. The two complexes exhibit weak red fluorescence of Sm3+ ions at room temperature, and the experimental results show that inert fluorescence lanthanide ions can influence the fluorescence of the complexes. |
