An unexpected oxidation: NaK₅Cl₂(S₂O₆)₂ revisited.

ABSTRACT: The title compound, NaK₅Cl₂(S₂O₆)₂ [systematic name: sodium penta-potassium dichloride bis-(di-thio-nate)], arose as an unexpected product from an organic synthesis that used di-thio-nite (S₂O₄^2-) ions as a reducing agent to destroy excess permanganate ions. Compared to the previous study [Stanley (1953 ▸). Acta Cryst.6, 187-196], the present tetra-gonal structure exhibits a root 2a × root 2a × c super-cell due to subtle changes in the orientations of the di-thio-nate anions. The structure can be visualized as a three-dimensional framework of [001] columns of alternating trans-NaO₄Cl₂ and KO₄Cl₂ octa-hedra cross-linked
