通过水热合成的方法,制备了一个新型的镉配合物{[Cd(BDC)(L)]·1.5H2O]n(1)(L=N,N'-双(3-吡啶)-5-羟基苯-1,3-二甲酰胺、H2BDC=对苯二甲酸),并且通过单晶X射线衍射对配合物进行了结构的表征.分析结果表明,配合物1属于单斜晶系:C2/c,a=2.171 45(8),b=1.605 34(6),c=1.678 04(6) nm,Z=8,V=5.116 8(3) nm3,Dc=1.656 g-cm-3,F(000)=2 568,μ=0.914 mm-1,R=0.026 5,wR=0.067 6.结构分析表明每个Cd(Ⅱ)与2个配体上的吡啶N原子以及来自2个不同BDC上的4个氧原子形成六配位模式.BDC阴离子与Cd(Ⅱ)交替连接成(Cd-BDC)n链,该链通过成对的L拓展成具有平行互穿模式的二维63网络.研究了配合物1的相纯度、热稳定性、固态荧光性质以及对Fe3+和二氯甲烷的传感行为.%A new Cd(Ⅱ) coordination polymer {[Cd(BDC)(L)]· 1.5H2O}n (1) [L=N,N'-bis (4-pyridin-3-yl)-5-hydroxyi-sophthalamide,H2BDC =1,4-benzenedicarboxylic acid) has been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction analysis.Complex 1 crystalizes in monoclinic,space group C2/c:a=2.171 45(8),b=1.605 34(6),c=1.678 04(6) nm,Z=8,V=5.116 8(3) nm3,Dc=1.65 6 g·cm-3,F(000)=2 568,μ=0.914 mm-1,the final R=0.026 5 and wR=0.067 6.The crystal structure analysis indicates that the Cd(lⅡ) cation is six-coordinated by two pyridyl N atoms from two L ligands,four O atoms from two BDC anions.The BDC anions connects adjacent Cd(Ⅱ) ions to form 1D chain,which is linked by pairs of L to generate two-dimensional 63 connected layer with a 2-fold parallel-interpenetrated structure.The phase purity,thermal stability,fluorescent property of 1 and fluorescence sensing properties of 1 for Fe3+ and dichloromethane have been studied investigated.CCDC:1847700.
