KMnO6I crystallizes in the trigonal P312 space group. K(1) is bonded to six equivalent O(1) atoms to form distorted KO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra and corners with six equivalent I(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-53°. Mn(1) is bonded to six equivalent O(1) atoms to form MnO6 octahedra that share corners with six equivalent K(1)O6 octahedra and edges with three equivalent I(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. O(1) is bonded in a distorted trigonal planar geometry to one K(1), one Mn(1), and one I(1) atom. I(1) is bonded to six equivalent O(1) atoms to form IO6 octahedra that share corners with six equivalent K(1)O6 octahedra and edges with three equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 51°.
