The structure described by Rb2LiVO4 crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Li(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form LiO4 tetrahedra that share corners with two equivalent V(1)O4 tetrahedra and  an edgeedge with one V(1)O4 tetrahedra. V(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form VO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra and  an edgeedge with one Li(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Rb(1), two equivalent Rb(2), one Li(1), and one V(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Li(1), and one V(1) atom. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), one Li(1), and one V(1) atom. is represented by the CIF card [CIF]
