The material structure described by RbMg6La crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(2), and two equivalent La(1) atoms to form RbLa2Mg10 cuboctahedra that share corners with four equivalent La(1)Rb2Mg10 cuboctahedra, corners with six equivalent Rb(1)La2Mg10 cuboctahedra, edges with two equivalent La(1)Rb2Mg10 cuboctahedra, faces with two equivalent Rb(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)Rb2Mg10 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to two equivalent Rb(1), one Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent La(1) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to two equivalent Rb(1), one Mg(2), one Mg(3), one Mg(4), two equivalent Mg(1), and two equivalent La(1) atoms. In the third Mg site, Mg(3) is bonded in a 8-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), and two equivalent La(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 8-coordinate geometry to two equivalent Rb(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. La(1) is bonded to two equivalent Rb(1), two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms to form LaRb2Mg10 cuboctahedra that share corners with four equivalent Rb(1)La2Mg10 cuboctahedra, corners with six equivalent La(1)Rb2Mg10 cuboctahedra, edges with two equivalent Rb(1)La2Mg10 cuboctahedra, faces with two equivalent Rb(1)La2Mg10 cuboctahedra, and faces with two equivalent La(1)Rb2Mg10 cuboctahedra. is represented by the CIF card [CIF]
