| 摘要: 在水热条件下,5-(4-吡啶基)四氮唑(4-PTZ)分别与氯化锌和氯化镉反应,得到2个基于此配体的配位聚合物,它们的分子式分别为{[Zn(4-PTZ)2Cl2]·4H2O}n(1)和{[Cd3(4-PTZ)2(H2O)2Cl6]·3H2O}n(2),且表现出不同的配位模式.这2个化合物均结晶在单斜晶系,化合物1的晶胞参数分别为:a=0.69175(8)nm;b=2.6688(3)nm;c=1.12266(12)nm;β=93.5350(10)°;V=2.0687(4)nm3;Z=4;R1=0.0318(I>2σ(I));wR2=0.0829;空间群为P21/n.化合物2的晶胞参数分别为:a=1.89713(13)nm;b=1.05579(7)nm;c=1.44649(10)nm;β=102.4890(10)°;V=2.8287(3)nm3;Z=4;R1=0.0262(I>2σ(I));wR2=0.1343;空间群为C2/c.通过元素分析、红外光谱分析和热重分析对该化合物进行了表征,另外荧光测定结果显示化合物1和2的固态粉末在室温下均表现出较强的紫外荧光发射特性. |

| Abstract: Two mixed metal-organic coordination polymers, namely {[Zn(4-PTZ)2Cl2]·4H2O}n (1) and {[Cd3(4-PTZ)2(H2O)2Cl6]·3H2O}n (2), were synthesized under hydrothermal condition using5-(4-pyridyl)tetrazolate (4-PTZ), which exhibited diverse coordination modes in two complexes. The two compounds are both crystallized in a monoclinic system. Compound 1: a=0.69175(8) nm; b=2.6688(3) nm; c=1.12266(12) nm; β=93.5350(10)°; V=2.0687(4) nm3; Z=4; R1=0.0318 for I>2σ(I); wR2=0.0829; space group P21/n. Compound 2: a=1.89713(13) nm; b=1.05579(7) nm; c=1.44649(10) nm; β=102.4890(10)°; V=2.8287(3) nm3; Z=4; R1=0.0262 for I>2σ(I); wR2=0.1343; space group C2/c. They are characterized by elemental analysis, IRspectroscopy and TGA. In addition, 1 and 2 have ultraviolet fluorescence emissions in the solid state at room temperature.
