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.
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°. There are four shorter (2.77 Å) and two longer (2.79 Å) K(1)-O(1) bond lengths. Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Mn(1)-O(1) bond lengths are 1.94 Å. O(1) is bonded in a 5-coordinate geometry to three equivalent K(1) and two equivalent Mn(1) atoms.
