镉盐与不同的三唑配体，导致了一系列新的三唑镉化合物从零到三维变化。[Cd（2）（deatrz）（2）（H（2）O）Br（4）]（1）（deatrz = 3，5-diethyl-4-amino-1，2，4-triazole）是一种零维配合物，它以三唑配体和微量OH（2）为桥，通过氢键接触形成一维链。[[Cd（3）（deatrz）（2）Cl（6）（H（2）O）（2）].2H（2）O]（n）（2）、[[Cd（dmtrz）Cl（2）].1.5H（2）O]（n）（3）（dmtrz = 3，5-二甲基-1，2，4-三唑）和[[Cd（3）（deatrz）（4）Cl（2）（SCN）（4）].2H（2）O]（n）（4）是一维聚合链。2和4是由三唑配体和氯原子桥连的三核镉单元构成的，而3是由微（2）-Cl、微（3）-Cl和三唑桥组成，通过氢键交联得到三维骨架。[[Cd（3）（dmatrz）（4）（SCN）（6）]]（n）（5）（dmatrz = 3，5-二甲基-4-氨基-1，2，4-三唑）具有二维结构，其基本单元为三核金属阳离子通过三唑配体桥连。配合物[[Cd（dmtrz）（SCN）（2）]（n）（6）是N1，N2-双齿桥联三唑金属化合物中第一个三维的例子。六个配合物表现出六种N1，N2-三唑与单原子桥结合的桥连模式。2、4和5是通过三核金属离子簇构建的聚合物链和平面的前所未有的例子，而3是三唑-金属络合物中微（3）-Cl桥接模式的第一个例子。我们已经简要地讨论了不同的有机配体和阴离子的调谐的基础上的各种维数。
Cadmium salts with different triazole ligands have led to a series of novel triazole-cadmium compounds varying from zero- to three-dimensionality. [Cd(2)(deatrz)(2)(H(2)O)Br(4)] (1) (deatrz = 3,5-diethyl-4-amino-1,2,4-triazole) is a zero-dimensional complex which uses a triazole ligand together with micro-OH(2) as bridges to form a 1D chain via hydrogen-bonding contacts. [[Cd(3)(deatrz)(2)Cl(6)(H(2)O)(2)].2H(2)O](n) (2), [[Cd(dmtrz)Cl(2)].1.5H(2)O](n)(3) (dmtrz = 3,5-dimethyl-1,2,4-triazole), and [[Cd(3)(deatrz)(4)Cl(2)(SCN)(4)].2H(2)O](n)(4) are polymeric 1D chains. 2 and 4 were constructed via trinuclear cadmium units bridged by triazole ligands and chloride atoms, while 3 consists of micro(2)-Cl, micro(3)-Cl, and triazole bridges, cross-linked by hydrogen bonding to give a 3D framework. [[Cd(3)(dmatrz)(4)(SCN)(6)]](n)(5) (dmatrz = 3,5-dimethyl-4-amino-1,2,4-triazole) shows a two-dimensional structure whose fundamental units are trinuclear metal cations bridged via triazole ligands. The complex [[Cd(dmtrz)(SCN)(2)]](n)(6) is the first three-dimensional example in N1,N2-didentate-bridged triazole-metal compounds. Six complexes exhibit six types of bridging modes of N1,N2-triazole in combination with single-atom bridges. 2, 4, and 5 are the unprecedented examples of polymeric chains and planes constructed via trinuclear metal ion clusters, whereas 3 is the first example of the micro(3)-Cl bridging mode in triazole-metal complexes. We have briefly discussed the variety of dimensionalities based on the tuning of different organic ligands and anions.
