Rb2Li(OsO3)2 crystallizes in the trigonal R-3 space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Li(1) is bonded to six equivalent O(1) atoms to form distorted LiO6 octahedra that share edges with six equivalent Os(1)O6 octahedra. Os(1) is bonded to six equivalent O(1) atoms to form OsO6 octahedra that share edges with three equivalent Li(1)O6 octahedra and edges with three equivalent Os(1)O6 octahedra. O(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one Li(1), and two equivalent Os(1) atoms.
