The title compound has been synthesized under 4 GPa and at 500 ◦C from Na2O andMnO as starting materials. Rietveld refinement of the X-ray powder pattern indicates that Na6MnO4 is isostructural to Na6ZnO4 and thus is representing the second manifestation of an “isolated” [MnO4]6− anion after Na14Mn2O9. The compound crystallizes in the hexagonal system in space group P63mc (no. 186) with a = 7.6631(2) and c = 5.9013(2) ° A, V = 300.1 °A3, and Z = 2.
