Two products of the reactions of CuI with 1‐benzoyl‐3‐(4‐bromophenyl)thiourea and with 1‐benzoyl‐3‐(2‐iodophenyl)thiourea have been obtained and characterized, namely poly[[[1‐benzoyl‐3‐(4‐bromophenyl)thiourea‐κ S ]‐μ 3 ‐iodido‐copper(I)] acetone hemisolvate], {[CuI(C 14 H 11 BrN 2 OS)]·0.5C 3 H 6 O} n , and poly[μ 4 ‐iodido‐μ 3 ‐iodido‐[ N ‐(benzo[ d ]thiazol‐2‐yl)benzamide‐κ N ]dicopper(I)], [Cu 2 I 2 (C 14 H 10 N 2 OS)] n . Their structures, determined by single‐crystal X‐ray diffraction analysis, exhibit different stoichiometries and molecular organizations; however, both compounds are polymeric and possess close Cu…Cu contacts. The first product contains a (CuI) n double chain supported by the thiourea derivative coordinated via the S atom. In the second case, the ligand undergoes dehalogenation and cyclization to form N ‐(benzo[ d ]thiazol‐2‐yl)benzamide that serves as the N ‐donor ligand which is connected to both sides of a (CuI) n quadruple chain. In both hybrid inorganic chains, I atoms bridge three or four Cu atoms. The coordination centres adopt more or less distorted tetrahedral geometries. The structures of the (CuI) n kernels of the ribbons are similar to fragments of the layers in high‐pressure phase V copper(I) iodide. Only weak S…O, C—H…O, C—H…I and π–π interactions hold the ribbons together, allowing the formation of crystals.
