RbMoSbO6 crystallizes in the orthorhombic Ima2 space group. Rb(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms. Mo(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted MoO6 octahedra that share corners with two equivalent Mo(1)O6 octahedra and corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-45°. Sb(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-48°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one Rb(1) and two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Rb(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Rb(1), one Mo(1), and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Rb(1), one Mo(1), and one Sb(1) atom.
