Materials Data on KMnO2 by Materials Project
KMnO2 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- 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–O bond lengths. Mn3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Mn–O bond lengths are 1.94 Å. O2- is bonded in a 5-coordinate geometry to three equivalent K1+ and two equivalent Mn3+ atoms.
