چکیده
In the crystal structure of the title compound, (C(7)H(10)N)(2)[ZnBr(4)], the coordination geometry of the anion is approximately tetra-hedral and a twofold rotation axis passes through the Zn atom. The Zn-Br bond lengths range from 2.400 (2) to 2.408 (3) Å and the Br-Zn-Br angles range from 108.14 (6) to 115.15 (15)°. In the crystal structure, the [ZnBr(4)](2-) anion is connected to two cations through N-H⋯Br and H(2)C-H⋯Br hydrogen bonds, forming two-dimensional cation-anion-cation layers normal to the b axis. No significant Br⋯Br inter-actions [the shortest being 4.423 (4) Å] are observed in the structure.
