The crystal structure described by Mg6LaW crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) 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 W(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 La(1) atoms to form distorted MgLa2Mg10 cuboctahedra that share corners with six equivalent Mg(2)La2Mg10 cuboctahedra, faces with two equivalent Mg(2)La2Mg10 cuboctahedra, and faces with six equivalent W(1)La2Mg10 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 W(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted linear geometry to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent W(1) atoms. La(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Mg(2), four equivalent Mg(1), four equivalent Mg(3), and two equivalent W(1) atoms. W(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent La(1) atoms to form distorted WLa2Mg10 cuboctahedra that share corners with six equivalent W(1)La2Mg10 cuboctahedra, faces with two equivalent W(1)La2Mg10 cuboctahedra, and faces with six equivalent Mg(2)La2Mg10 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
