Mg6WZn crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), two equivalent W(1), and one Zn(1) atom. 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 Zn(1) atoms to form distorted MgMg10Zn2 cuboctahedra that share corners with six equivalent Mg(2)Mg10Zn2 cuboctahedra, faces with two equivalent Mg(2)Mg10Zn2 cuboctahedra, and faces with six equivalent W(1)Mg10Zn2 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 W(1), and two equivalent Zn(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted linear geometry to two equivalent Mg(2), 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 Zn(1) atoms to form WMg10Zn2 cuboctahedra that share corners with six equivalent W(1)Mg10Zn2 cuboctahedra, faces with two equivalent W(1)Mg10Zn2 cuboctahedra, and faces with six equivalent Mg(2)Mg10Zn2 cuboctahedra. Zn(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), four equivalent Mg(3), and two equivalent W(1) atoms.
