Di-μ-thio­semicarbazide-κ(4) S:S-bis­[bis­(thio­semicarbazide-κS)copper(I)] diiodide

The title compound, [Cu(2){SC(NH(2))NHNH(2)}(6)]I(2), was obtained by the reaction of CuI and thio­semicarbazide (TSCZ) in acetonitrile. Each Cu(I) ion is coordinated by four S atoms of the TSCZ ligands, forming a tetra­hedral geometry. Centrosymmetric dimers are formed by two coordination tetra­hedra sharing a common edge, with a Cu⋯Cu distance of 2.8236 (14) Å. The I(−) ion does not have any direct inter­action with the metal. The crystal structure is stabilized by weak N—H⋯N, N—H⋯S and N—H⋯I hydrogen bonds, forming a three-dimensional network structure.
