摘要： 在水热条件下, 以3-氨基-1,2,4-三唑-5-甲酸(AmTHZAC)为配体, 原位反应得到了两个镉的配位聚合物 Cd(AmTAZ)Cl(1)和[Cd(AmTAZ)(BDC)(H2O)2]·1.25H2O(2)(AmTAZH=3-amino-1,2,4-triazole, H2BDC=benzene-1,4-dicarboxylic acid), 采用红外光谱、差热-热重、CHN元素分析及单晶X射线衍射等手段对晶体结构进行了表征, 并研究了化合物1和2的荧光性质. 化合物1属正交晶系, P2(1)2(1)2(1)空间群, a=0.6452(3) nm, b=0.7848(5) nm, c=1.0449(6) nm, V=0.5291(5) nm3, Z=4, 最后一致性因子[I＞2σ(I)], R1=0.0226, wR2=0.0377, GOF=1.087. 化合物2属正交晶系, Pmc2(1)空间群, a=0.7100 nm, b=0.9920 nm, c=1.2561 nm, V=0.8847 nm3, Z=8, 最后一致性因子[I＞2σ(I)], R1=0.0934, wR2=0.2456, GOF=1.031.

Abstract: Two cadmiun coordination polymers Cd(AmTAZ)Cl(1) and [Cd(AmTAZ)(BDC)(H2O)2]·1.25H2O(2)(AmTAZH=3-amino-1,2,4-triazole, H2BDC=benzene-1, 4-dicarboxylic acid) were synthesized under hydrothermal in stiu conditions and characterized by IR, TG-DTA, CHN elemental analysis and single crystal X-ray diffraction analysis. The fluorescent properties of compounds 1 and 2 are also discussed. Compound 1 crystallizes in the triclinic space group P2(1)2(1)2(1) with a=0.6452(3) nm, b=0.7848(5) nm, c =1.0449(6) nm, V=0.5291(5) nm3, Z=4, R1=0.0226, wR2=0.0377, GOF=1.087. Compound 2 crystallizes in the orthorhombic space group Pmc2(1) with a=0.7100 nm, b=0.9920 nm, c=1.2561 nm, V=0.8847 nm3, Z=8, R1=0.0934, wR2=0.2456, GOF=1.031.
