n chains running along the a axis, which are surrounded by 1-ethyl-3-methylimidazolium cations. Three of the five unique Br atoms and one of the three Cu
I atoms occupy special positions with half-occupancy (a mirror plane perpendicular to the b axis, site symmetry m). The Cu
I ions are in a distorted tetrahedral coordination environment, with four Br atoms at distances ranging from 2.3667 14;(10) to 2.6197 14;(13) 14;Å, and an outlier at 3.0283 14;(12) 14;Å, exceptionally elongated and with a small contribution to the bond-valence sum of only 6.7%. Short C-H⋯Br contacts build up a three-dimensional network. The Cu⋯Cu distances within the chain range from 2.8390 14;(12) to 3.0805 14;(17) 14;Å, indicating the existence of weak Cu
I⋯Cu
I cuprophilic interactions.
