| 摘 要： | 采用水热法合成和组装具有发光性能的稀土金属配合物分子体系,得到了稀土与间苯二甲酸(H:isophth)配合物Ln2(isophth),(H2O)].(Ln=Eu,Tb)),这两个配合物都属于单斜晶系P2(1)/n点群.其x射线单晶衍射表明,两个Ln离子处于不同的配位环境中,Eu(1)和Tn(1)离子分别处于9配位的五角双锥和8配位双帽三棱柱配位构型,而Eu(2)和Tb(2)则处于7配位的单帽四方棱柱构型.荧光测试结果表明:二者呈现出较好的荧光性能.

| Abstract: | Two Eu(III) and Tb(III) complexes {Eu2(isophth)3(H2O)2}n(1),{TB2(isophth)3(H2O)2}n(2) had been obtained by hydrothermal reaction of lanthanide(III) nitrate and 1,3-benzendiicarboxylic acid,and were characterized by X-ray single-crystal diffraction.The crystal structure data revealled that they were isostructural.The two Ln3+ ions had different coordination environments.Eu(1) was coordinated with nine atoms in a distorted capped square prism geometry,while Tb(1) of complex 2 was liganted to eight atoms in a ... |
