Bromidotetra­kis­(2-ethyl-1H-imidazole-κN³)copper(II) bromide

The Cu^II 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.
