摘　　要：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·cm3, 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（Ⅱ） 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.
