Complex [Cu(tbt)Cl₂]_n (tbt = 1‐tert‐butyl‐1H‐tetrazole) was prepared by reaction of tbt with copper(II) chloride in solution. According to single‐crystal X‐ray analysis, this complex presents 1D coordination polymer, formed at the expense of double chlorido bridges between neighboring pentacoordinate copper(II) cations. 1‐tert‐Butyl‐1H‐tetrazole acts as monodentate ligand coordinated by Cu^II cations via the heteroring N⁴ atoms. The temperature‐dependent magnetic susceptibility measurements of novel complex [Cu(tbt)Cl₂]_n as well as described previously 1D coordination polymer [Cu(tbt)₂Cl₂]_n, and linear trinuclear complex [Cu₃(tbt)₆Br₆], were carried out. Magnetic studies revealed that the copper(II) ions were weakly ferromagnetically coupled in polymeric copper(II) chloride complexes, whereas complex [Cu₃(tbt)₆Br₆] showed antiferromagnetic coupling.

具有1-叔丁基-1H-四唑的卤代桥联铜（II）配合物：晶体结构和磁性

络合物[Cu（tbt）Cl ₂ ] _n（tbt = 1-叔丁基-1 H-四唑）是通过使tbt与氯化铜（II）反应生成的。根据单晶X射线分析，该络合物呈现一维配位聚合物，其形成是以牺牲相邻五配位铜（II）阳离子之间的双氯桥为代价的。1-叔丁基-1 H-四唑作为单齿配体，通过杂环N ⁴原子与Cu ^II阳离子配位。新型络合物[Cu（tbt）Cl ₂ ] _n的温度依赖性磁化率测量如前所述，进行一维配位聚合物[Cu（tbt）₂ Cl ₂ ] _n和线性三核络合物[Cu ₃（tbt）₆ Br ₆ ]。磁性研究表明，铜（II）离子在聚合氯化铜（II）配合物中呈弱铁磁耦合，而配合物[Cu ₃（tbt）₆ Br ₆ ]显示出反铁磁耦合。
