RbLiMoO4 crystallizes in the monoclinic Cc space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Mo(1)O4 tetrahedra. Mo(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form MoO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Rb(1), one Li(1), and one Mo(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Rb(1), one Li(1), and one Mo(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Li(1), and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Li(1), and one Mo(1) atom.
