A new organic-inorganic hybrid compound, catena-poly-[bis(1-ethyl-3-methylimidazolium) [5-bromido-tri-3-bromido-tri-2-bromido-pentacuprate(I)]], {(C6H11N2)2[Cu5Br7]}n,has been obtained under ionothermal conditions from areaction mixture containing Ba(OH)28H2O, Cu(OH)22H2O,As2O5, 1-ethyl-3-methylimidazolium bromide and distilledwater. The crystal structure consists of complex [Cu5Br7]2anions arranged in sinusoidal {[Cu5Br7]2}n chains runningalong the a axis, which are surrounded by 1-ethyl-3-methylimidazoliumcations. Three of the five unique Br atoms andone of the three CuI atoms occupy special positions with halfoccupancy(a mirror plane perpendicular to the b axis, sitesymmetry m). The CuI ions are in a distorted tetrahedralcoordination environment, with four Br atoms at distancesranging from 2.3667 (10) to 2.6197 (13) A ° , and an outlier at3.0283 (12) A ° , exceptionally elongated and with a smallcontribution to the bond-valence sum of only 6.7%. ShortC-H Br contacts build up a three-dimensional network.The Cu Cu distances within the chain range from2.8390 (12) to 3.0805 (17) A ° , indicating the existence of weakCuI CuI cuprophilic interactions.
