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

Abstract: The title compound, [Cu₂{SC(NH₂)NHNH₂}₆]I₂, 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 CuCu 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-HN, N-HS and N-HI hydrogen bonds, forming a three-dimensional network structure.
