Abstract

The title salt, [Mn(C₂H₆OS)₆]I₄, is made up from discrete [Mn(DMSO)₆]²⁺ (DMSO is dimethyl sulfoxide) units connected through non-classical hydrogen bonds to linear I₄^2- tetra-iodide anions. The Mn^II ion in the cation, situated on a position with site symmetry -3., is octa-hedrally coordinated by O atoms of the DMSO mol-ecule with an Mn-O distance of 2.1808 (12) Å. The I₄^2- anion contains a neutral I₂ mol-ecule weakly coordinated by two iodide ions, forming a linear centrosymmetric tetra-iodide anion. The title compound is isotypic with the Co, Ni, Cu, and Zn analogues.

Keywords: crystal structure; isotypism; octahedral coordination; tetraiodide.
