The crystal structure described by Na3MnO3 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted corner-sharing NaO4 tetrahedra. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one O(1) and three equivalent O(2) atoms. Mn(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Na(2), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded to one Na(1), three equivalent Na(2), and one Mn(1) atom to form a mixture of distorted corner and edge-sharing ONa4Mn trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
