The material structure described by RbLiCrO4 crystallizes in the trigonal P31c space group. Rb(1) is bonded in a 9-coordinate geometry to three equivalent O(2) and six equivalent O(1) atoms. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Cr(1)O4 tetrahedra. Cr(1) is bonded to one O(2) and three equivalent O(1) atoms to form CrO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one Li(1), and one Cr(1) atom. In the second O site, O(2) is bonded in a linear geometry to three equivalent Rb(1), one Li(1), and one Cr(1) atom. is represented by the CIF file [CIF]
