Abstract:

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-κS]-μ3-iodido-copper(I)] acetone hemisolvate], {[CuI(C14H11BrN2OS)]·0.5C3H6O}n, and poly[μ4-iodido-μ3-iodido-[N-(benzo[d]thiazol-2-yl)benzamide-κN]dicopper(I)], [Cu2I2(C14H10N2OS)]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.
