The material structure described by Mg6LaSn crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 11-coordinate geometry to one Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), two equivalent La(1), and two equivalent Sn(1) atoms. In the second Mg site, Mg(2) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Sn(1) atoms to form distorted MgMg10Sn2 cuboctahedra that share corners with six equivalent Mg(2)Mg10Sn2 cuboctahedra, edges with four equivalent Mg(4)La2Mg10 cuboctahedra, faces with two equivalent Mg(4)La2Mg10 cuboctahedra, faces with two equivalent Mg(2)Mg10Sn2 cuboctahedra, and faces with six equivalent La(1)Mg10Sn2 cuboctahedra. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), two equivalent La(1), and two equivalent Sn(1) atoms. In the fourth Mg site, Mg(4) is bonded to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent La(1) atoms to form distorted MgLa2Mg10 cuboctahedra that share corners with four equivalent La(1)Mg10Sn2 cuboctahedra, corners with six equivalent Mg(4)La2Mg10 cuboctahedra, edges with two equivalent La(1)Mg10Sn2 cuboctahedra, edges with four equivalent Mg(2)Mg10Sn2 cuboctahedra, faces with two equivalent Mg(4)La2Mg10 cuboctahedra, faces with two equivalent Mg(2)Mg10Sn2 cuboctahedra, and faces with two equivalent La(1)Mg10Sn2 cuboctahedra. La(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Sn(1) atoms to form LaMg10Sn2 cuboctahedra that share corners with four equivalent Mg(4)La2Mg10 cuboctahedra, corners with six equivalent La(1)Mg10Sn2 cuboctahedra, edges with two equivalent Mg(4)La2Mg10 cuboctahedra, faces with two equivalent Mg(4)La2Mg10 cuboctahedra, faces with two equivalent La(1)Mg10Sn2 cuboctahedra, and faces with six equivalent Mg(2)Mg10Sn2 cuboctahedra.
