The crystal structure described by RbLiMg6 crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms to form a mixture of corner and face-sharing RbLi2Mg10 cuboctahedra. Li(1) is bonded in a 8-coordinate geometry to two equivalent Rb(1), two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Rb(1), one Li(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Li(1), two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to two equivalent Rb(1), two equivalent Li(1), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), and two equivalent Mg(4) atoms. In the fourth Mg site, Mg(4) is bonded in a 12-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), four equivalent Mg(1), and four equivalent Mg(3) atoms. is represented by the CIF file [CIF]
