Bromidotetrakis(2-ethyl-1H-imidazole-κN3)copper(II) bromide
Abstract
The CuII ion in the title molecular salt, [CuBr(C5H8N2)4]Br, is coordinated in a square-pyramidal geometry by four N atoms of imidazole ligands and one bromide anion in the apical position. In the crystal, the ions are linked by N—H...Br hydrogen bonds involving both the coordinating and the free bromide species as acceptors. A C—H...Br interaction is also observed. Overall, a three-dimensional network results.
