KO2 crystallizes in the cubic Pa-3 space group. K(1) is bonded to six equivalent O(1) atoms to form KO6 octahedra that share corners with twelve equivalent K(1)O6 octahedra and corners with six equivalent O(1)K3O tetrahedra. The corner-sharing octahedral tilt angles are 75°. O(1) is bonded to three equivalent K(1) and one O(1) atom to form OK3O tetrahedra that share corners with three equivalent K(1)O6 octahedra and corners with fifteen equivalent O(1)K3O tetrahedra. The corner-sharing octahedral tilt angles are 66°.
