The structure described by Na3MnO4 crystallizes in the cubic P2_13 space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted T-shaped geometry to three equivalent O(2) atoms. In the second Na site, Na(2) is bonded in a distorted rectangular see-saw-like geometry to one O(1) and three equivalent O(2) atoms. In the third Na site, Na(3) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. Mn(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Na(2) and one Mn(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Na(1), one Na(2), one Na(3), and one Mn(1) atom. is represented by the CIF file [CIF]
