The crystal structure described by K2NaMnO4 crystallizes in the orthorhombic Fddd space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Mn(1) is bonded in a tetrahedral 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 one K(1), three equivalent K(2), one Na(1), and one Mn(1) atom. In the second O site, O(2) is bonded in a 7-coordinate geometry to one K(2), three equivalent K(1), two equivalent Na(1), and one Mn(1) atom. is represented by the CIF card [CIF]
