Five coordination compounds assembled from the pyridyl based ligand, Ni(PBN)₄(N₃)₂, 1; {[Co(PPT)₂·(H₂O)₂]·2H₂O}_n, 2; [Cu(PPT)]_n, 3; {[Zn₂(PPT)₃(OH)]·2H₂O}_n, 4, and [Cd(PPT)₂]_n, 5 (PPT = 5-(3-pyridylphenyl)tetrazole and PBN = 4-(3-pyridyl)benzonitrile) have been solvothermally synthesized and characterized by single-crystal X-ray diffraction, powder XRD, elemental analysis, IR spectroscopy, solid state fluorescence and TG analysis. The PPT ligand in the complexes is generated via the in situ [2 + 3] cycloaddition in the reaction of the cyano groups of the organonitrile and sodium azide. Single-crystal X-ray diffraction analyses reveal compound 1 is an oligomer of 6-coordinated Ni(II) compound where the 6 coordination sites are occupied by six nitrogen atoms from four distinct PBN ligands and two azide ions, respectively. Compound 2 exhibits a 1D chain structure where the 6-coordinated cobalt centers are double connected by two upside down μ₂-PPT ligands. Both compound 3 and compound 4 present the 2D sheet structures constructed by μ₂-tetrazole-linked copper(I) dimmer and μ₂-hydroxy-connected zinc(II) dimmer, respectively, with both centers of 4-coordinated fashions. Compound 5 is a dense 3D framework with the PPT ligand of a μ₃-bridging mode. Structural analyses indicate the structural varieties of the dimensionalities in these compounds result from the coordination diversity of the PPT ligands. In addition, compound 3 represents a rare example of copper(II) that is experienced the self-reduction process during the in situ [2 + 3] cycloaddition and exhibits a blue emission at room temperature. Thermal stability analyses indicate the compounds 4 and 5 are stable up to 300 °C and the temperature dependent PXRD reveal the residues of compounds 4 and 5 are ZnO and CdCO₃, respectively.

从基于吡啶基配体组装五种配位化合物，镍（PBN）₄（N ₃）₂，1 ; {[Co（PPT）₂ ·（H ₂ O）₂ ]·2H ₂ O} _n，2；[Cu（PPT）] _n，3 ; {[Zn ₂（PPT）₃（OH）]·2H ₂ O} _n，4和[Cd（PPT）₂ ] _n，5（PPT = 5-（3-吡啶基苯基）四唑和PBN = 4-（3-吡啶基）苄腈）溶剂热合成并通过单晶X射线衍射，粉末XRD，元素分析，IR光谱，固态荧光表征和TG分析。配合物中的PPT配体是通过有机腈和叠氮化钠的氰基反应中的原位[2 + 3]环加成反应生成的。单晶X射线衍射分析表明，化合物1是6位配位的Ni（II）化合物的低聚物，其中6个配位位点分别被来自四个不同的PBN配体和两个叠氮化物离子的六个氮原子占据。化合物2呈现一维链结构，其中6个配位的钴中心通过两个上下颠倒的μ双连接₂ -PPT配体。两个化合物3和化合物4本由构建的2D片材结构μ ₂ -四唑联铜（I）的调光器和μ ₂分别-羟基连接的锌（II）的调光器，具有4配位的时装两个中心。化合物5是具有的PPT配体的致密的三维框架μ ₃ -bridging模式。结构分析表明，这些化合物中维数的结构变化是由PPT配体的配位多样性引起的。另外，化合物3代表了一个难得的铜（II）实例，该铜在原位[2 + 3]环加成过程中经历了自还原过程，并且在室温下呈现蓝色发射。热稳定性分析表明，化合物4和5在高达300°C的温度下都稳定，并且温度依赖性PXRD表明化合物4和5的残基分别为ZnO和CdCO ₃。
