介绍了一种单核镉配合物和五种新型1,2,4-三唑苯甲酸酯配位聚合物的合成和晶体结构。化合物（∞）(3)[Cd(H- me -trz-pba)(2)](2),(∞)(3)[Cd(me - me -trz-pba)(2)](4)和（∞）(3)[Zn(H- me -trz-pba)(2)](6)可以通过溶剂热合成或在适当的溶剂中对起始材料进行简单加热得到，也可以通过配合物[Cd(H- me -trz-pba)(2)(H(2)O)(4)](1)，一维（1D）配位聚合物（∞）(1)[Cd(Me-3py-trz-pba)(2)(H(2)O)(2)]·H(2)O(3)](3)进行热转化。多孔三维（3D）骨架（∞）(3)[Zn(H-Me-trz-pba)2]·4H(2)O(5)。这些转化的驱动力是形成热稳定、无孔、结晶的三维配位聚合物。结构转变伴随着水的流失，揭示了三唑苯甲酸酯配体重排引起的金属离子配位球的显著变化。化合物2、4、5和6表现出4倍和5倍的金刚石网络（直径）相互渗透，并且在380°C下热稳定。
The syntheses and crystal structures of a mononuclear cadmium complex and five novel coordination polymers based on 1,2,4-triazolyl benzoates are presented. The compounds (∞)(3)[Cd(H-Me-trz-pba)(2)] (2), (∞)(3)[Cd(Me-3py-trz-pba)(2)] (4), and (∞)(3)[Zn(H-Me-trz-pba)(2)] (6) can be obtained by solvothermal synthesis or simple heating of the starting materials in appropriate solvents, and are also accessible by thermal conversion of the complex [Cd(H-Me-trz-pba)(2)(H(2)O)(4)] (1), the one-dimensional (1D) coordination polymer (∞)(1)[Cd(Me-3py-trz-pba)(2)(H(2)O)(2)]·H(2)O (3), and the porous three-dimensional (3D) framework (∞)(3)[Zn(H-Me-trz-pba)2]·4H(2)O (5), respectively. The driving force for these conversions is the formation of thermally stable, nonporous, crystalline 3D coordination polymers. The structural transformations are accompanied by the loss of water and reveal significant changes of the coordination spheres of the metal ions caused by a rearrangement of the triazolyl benzoate ligands. Compounds 2, 4, 5, and 6 exhibit 4- and 5-fold interpenetration of diamondoid networks (dia) and are thermally stable up to 380 °C.
