英文摘要	在体积比为1∶1乙醇水溶液中,采用常规溶液法合成了一种镧的配合物[lA(nO3)(PHEn)2(dHb)2],其中,HdHb=2,6-二羟基苯甲酸。利用元素分析、Ir、Pl、Tg和X射线单晶衍射分析进行了表征。结果表明:晶体属单斜晶系,P21/n空间群,A=1.12404(2)nM,b=2.66197(5)nM,C=1.14734(2)nM,β=101.8482(18)°,V=3.3599(1)nM3,z=4,r1=0.0224,Wr2=0.0556。十配位的lA(Ⅲ)处于四帽反三棱柱的多面体环境,配合物通过π-π堆积作用扩展为三维的超分子体系。配合物与配体HdHb具有类似的荧光性能。; A new lanthanum(Ⅲ) complex [La(NO3)(phen)2(DHB)2](HDHB=2,6-dihydroxybenzoic acid) was synthesized in ethanol water which was composed of 1∶ 1(V/V),by the conventional solution method,at room temperature,and structurally characterized by elemental analysis,IR,PL,TG and single crystal X-ray diffraction.The results showed that the complex is monoclinic system,space group P21/n,a=1.12404(2) nm,b=2.66197(5) nm,c=1.14734(2) nm,β=101.8482(18)°,V=3.3599(1) nm3,Z=4,R1=0.0224,wR2=0.0556.The π-π packing interactions make the complex molecules into a 3D supramolecule network,in which the ten-coordinated LaN4O6 cores exhibit a quadruply capped trigonal prismatic geometry.The fluorescence properties of the lanthanum(Ⅲ) complex are similar to ligand HDHB.
