| Аннотация: | ,3-Bis(1-methyl-1H-tetrazol-5-yl)propane (bmtp) was prepared by a procedure including regioselective tert-butylation of 1,3-bis(1H-tetrazol-5-yl)propane and exhaustive methylation of the obtained 1,3-bis(2-tert-butyl-1H-tetrazol-5-yl)propane, followed by removal of the tert-butyl group from the tetrazolium salt under acidic conditions. The ligand bmtp reacts with CuCl<sub>2</sub>·2H<sub>2</sub>O in ethanol to give the complexes [Cu<sub>3</sub>(bmtp)<sub>2</sub>Cl<sub>6</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub>n</sub> and [Cu(bmtp)Cl<sub>2</sub>]<sub>n</sub>. The transformation of [Cu(bmtp)Cl<sub>2</sub>]<sub>n</sub> into [Cu<sub>3</sub>(bmtp)<sub>2</sub>Cl<sub>6</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub>n</sub> is observed in ethanol. According to single crystal X-ray analysis, [Cu(bmtp)Cl<sub>2</sub>]<sub>n</sub> was obtained as a mixture of polymorphic forms. They are all 1D coordination polymers, in which polymeric chains include Cu<sub>2</sub>Cl<sub>4</sub> units linked to each other by two bridging ligands via the tetrazole ring N<sup>4</sup> atoms. [Cu<sub>3</sub>(bmtp)<sub>2</sub>Cl<sub>6</sub>(H<sub>2</sub>O)<sub>2</sub>]<sub>n</sub> presents a 2D coordination polymer, including Cu<sub>3</sub>Cl<sub>6</sub> units bonded to four others by ligand molecules. In this complex, the tetrazole ligands show monodentate N<sup>4</sup> and bridging N<sup>3</sup>,N<sup>4</sup> coordination. The temperature-dependent magnetic susceptibility measurements of this complex revealed that the copper(II) ions are antiferromagnetically coupled, showing a coupling constant J of −4.0 |
