title: catena-Poly[[[bis-(thio-urea-κS)copper(I)]-μ-thio-urea-κS:S] iodide acetonitrile hemisolvate].
abstract: The title complex, {[Cu(CH(4)N(2)S)(3)]I·0.5CH(3)CN}(n), was formed by the reaction of CuI and thio-urea in acetonitrile. There are two independent Cu(I) ions in the asymmetric unit which are coordinated by two terminal and two bridging thio-urea ligands to form a one-dimensional helical chain structure progagating in the a-axis direction. Each Cu(I) ion is in a distorted tetra-hedral coordination environment. The crystal structure is stabilized by weak N-H⋯S and N-H⋯I hydrogen bonds.
