The material structure described by K3MnO3 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the third K site, K(3) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. Mn(1) is bonded in a distorted see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one K(1), one K(2), two equivalent K(3), and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to one K(3), two equivalent K(1), two equivalent K(2), and one Mn(1) atom. In the third O site, O(3) is bonded to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one Mn(1) atom to form distorted edge-sharing OK6Mn pentagonal bipyramids. is represented by the CIF file [CIF]
