KOs2O6 crystallizes in the cubic Fd-3m space group. K(1) is bonded to six equivalent O(1) atoms to form KO6 octahedra that share corners with twelve equivalent Os(1)O6 octahedra. The corner-sharing octahedral tilt angles are 70°. Os(1) is bonded to six equivalent O(1) atoms to form OsO6 octahedra that share corners with six equivalent K(1)O6 octahedra and corners with six equivalent Os(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-70°. O(1) is bonded in a 2-coordinate geometry to one K(1) and two equivalent Os(1) atoms.
