The material described by KOsF6 crystallizes in the trigonal R-3 space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with six equivalent Os(1)F6 octahedra, edges with six equivalent K(1)F12 cuboctahedra, and faces with two equivalent Os(1)F6 octahedra. The corner-sharing octahedral tilt angles are 41°. Os(1) is bonded to six equivalent F(1) atoms to form OsF6 octahedra that share corners with six equivalent K(1)F12 cuboctahedra and faces with two equivalent K(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Os(1) atom. is represented by the CIF file [CIF]
