Octasodium hexatungstomanganate(IV) octadecahydrate

A. L. Nolan, R. C. Burns, G. A. Lawrance and D. C. Craig

Synopsis: The single-crystal structure of the title compound shows the anion to have the Anderson structure based on six WO₆ octahedral edge-sharing units surrounding a central MnO₆ octahedron. Varying interactions from the O atoms of the MnO₆ octahedron to surrounding water molecules result in differences in the Mn-O distances.
