The Synthesis and Characterization of a Supramolecular Compound { Cd (H2 dtca) (bipy) }

利用1,3-二(2',4'-二羧酸苯基)苯、2,2'-联吡啶和氧化镉在水热条件下反应制备了一种新型超分子化合物{ Cd(H2dtca) (bipy)}[H2dtca=1,3-二(2',4'-二羧酸苯基)苯,bipy=2,2'-联吡啶].通过X-射线单晶衍射测定了化合物的晶体结构,并利用元素分析、红外光谱等技术对其进行表征.结构研究发现该晶体属于单斜晶系P21/n空间群,a=1.604 06(7) nm,b=1.037 30(4)nm,c=1.720 97(7) nm;β=101.803 0(10)°;Z=4,wR1=0.034 2,wR2 =0.079 5.晶体结构分析表明2个镉在1个1,3-二(2',4'-二羧酸苯基)苯的连接下形成了一个双核结构,再在氢键作用下,形成3维超分子结构.此外,还研究了配合物的固态荧光性质.
A new supermolecular compound {Cd2(H2dtca)2(bipy)2} [H2dtca=1,3-di(2',4'-dicarboxypheny)-benzene,bipy=2,2'-bipyridine] was synthesized hydrothermally and characterized by means of elemental analysis,IR and single crystal X-ray diffraction.Complex crystallizes in monoclinic space group P21/n,a=1.604 06(7)nm,b=1.037 30(4)nm,c=1.720 97(7)nm; β=101.803 0(10)°; Z=4,wR1=0.034 2,wR2=0.079 5.The crystal structure of compound revealed that one 1,3-di(2',4'-dicarboxypheny)benzene ligand links two Cd ions to form a symmetrical dimmer,and the binuclear units form a 3D supramolecular structure under the action of the hydrogen bonds.The luminescence property in solid state of complex have been further studied and discussed in this paper
