BaMg6Zn crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Zn(1) atoms to form a mixture of face and corner-sharing BaMg10Zn2 cuboctahedra. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 3-coordinate geometry to two equivalent Ba(1), two equivalent Mg(3), two equivalent Mg(4), and one Zn(1) atom. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to two equivalent Mg(4) and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 10-coordinate geometry to two equivalent Ba(1), one Mg(3), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), and two equivalent Zn(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Ba(1), two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. Zn(1) is bonded in a 8-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), and four equivalent Mg(3) atoms.
