配合物Cd(bpndc)(phen)2(H2O)·2H2O的水热合成、晶体结构及荧光性质

摘要

A new cadmium complex [Cd(bpndc)(phen)2(H2O)]· 2H2O (1) was obtained by hydrothermal assembly of Cd(NO3)2·4H2O with a benzophenone-4,4′-dicarboxylic acid (H2bpndc) in the presence of N-donor ligands,1,10-phenanthroline (phen).Complex 1 crystallizes in tetragonal,space group I41/awith a=3.15869(16)nm,b=3.158 69(16) nm,c=1.54459(17) nm,V=15.411 (3) nm3,Z=16,C39H30N4CdO8,Mr=795.07,Dc=1.371 g·cm-3,μ=0.621 mm,F(000)=6464,Rint=0.0727,R1=0.052 3,wR2=O.116 6.Single-crystal X-ray diffraction analysis revealed that each metal center located in a distorted octahedron coordination environment,and it is further connected by hydrogen-bond interactions to give a one-dimensional (1D) supramolecular structure.In addition,the luminescent property of complex 1 has been investigated at room temperature.CCDC:827905.%由二苯甲酮-4,4′-二甲酸和邻菲咯啉为配体合成了1个新的镉化合物[Cd(bpndc)(phen)2(H2O)]· 2H2O (1)(H2bpndc=二苯甲酮-4,4′-二甲酸),并对其进行了元素分析、IR及x-射线衍射法表征.晶体结构表明:配合物1属于四方晶系,I41/a空间群.配合物1中心镉原子是六配位的变形八面体构型,该单核化合物通过氢键拓展成一维链状结构.配合物1的荧光测试研究表明它具有蓝色荧光.
