The material structure described by KMnO2 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form a mixture of corner and edge-sharing MnO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent K(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to four equivalent K(1) and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
