Hexa­kis­(dimethyl sulfoxide-[kappa]O)zinc(II) poly­iodide

L. Garzón-Tovar, Á. Duarte-Ruiz and P. E. Fanwick

Abstract: The title compound, [Zn{(CH3)2SO}6]I4, is a one-dimensional supra­molecular polymer along a threefold rotation axis of the space group. It is built up from discrete [Zn{(CH3)2SO}6]2+ units connected through non-classical hydrogen bonds to linear I42- polyiodide anions (C-H...I = 3.168 Å). The ZnII ion in the cation has an octa­hedral coordination geometry, with all six Zn-O bond lengths being equivalent, at 2.111 (4) Å. The linear polyiodide anion contains a neutral I2 mol­ecule weakly coordinated to two iodide ions.
