The material structure described by NaMnO4 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to one O(4), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NaO7 pentagonal bipyramids that share corners with two equivalent Na(1)O7 pentagonal bipyramids, corners with seven equivalent Mn(1)O4 tetrahedra, and edges with two equivalent Na(1)O7 pentagonal bipyramids. Mn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form MnO4 tetrahedra that share corners with seven equivalent Na(1)O7 pentagonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one Mn(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Mn(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Mn(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one Mn(1) atom. is represented by the CIF card [CIF]
