The compound described by KMnO2 crystallizes in the orthorhombic Pnnm space group. K(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing KO6 octahedra. The corner-sharing octahedral tilt angles are 57°. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to three equivalent K(1) and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
