摘要
采用低温水热法合成了一个新的镧(Ⅲ)配位聚合物{[La(phen-dione)2(H2dhtp)0.5(H2O)]·H2O}n(phen-dione=1,10-邻菲啰啉-5,6-二酮,H2dhtp=2,5-二羟基对苯二甲酸酯)。单晶衍射分析结果表明,该配合物属三斜晶系,P-1空间群,晶胞参数为a=9.4600(19)nm,b=11.810(2)nm,c=12.280(3)nm,α=93.34(3)°,β=106.74(3)°,γ=103.21(3)°,V=1267.7(5)nm^3,D c=1.806 g/cm^3,Z=2,μ=1.752 mm^-1,F(000)=678。用X-射线单晶衍射、元素分析、IR、TG和荧光光谱对配合物进行了表征。测量晶体的荧光光谱特性发现,该配合物在488 nm和532 nm有较强的荧光发射峰。
A new lanthanum(III)coordination polymer{[La(phen-dione)2(H2dhtp)0.5(H2O)]·H2O}n(phen-dione=1,10-phenanthroline-5,6-dione,H2dhtp=2,5-dihydroxyterephthalate)was synthesized by hydrothermal method.Single crystal analysis shows complex crystallizes in triclinic system,P-1 space group with a=9.4600(19)nm,b=11.810(2)nm,c=12.280(3)nm,α=93.34(3)°,β=106.74(3)°,γ=103.21(3)°,V=1267.7(5)nm^3,D c=1.806 g/cm^3,Z=2,μ=1.752 mm^-1,F(000)=678.The coordination polymer has been structurally characterized by X-ray single crystal diffraction,elemental analysis,IR,TG and fluorescence spectra.The fluorescence spectra of the crystal show that the complex has strong fluorescence emission peaks at 488 nm and 532 nm.
