| Abstract: | 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 CuII 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. |
