RbOsO3 is Ilmenite structured and crystallizes in the triclinic P-1 space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Os(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted edge-sharing OsO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Os(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Os(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1) and two equivalent Os(1) atoms.
