The compound described by KMnO2 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Mn(1) is bonded to two equivalent O(1) and three equivalent O(2) atoms to form edge-sharing MnO5 square pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent K(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent Mn(1) atoms. is represented by the CIF card [CIF]
