The material structure described by Mg6CeW 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 Ce(1), and two equivalent W(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Ce(1) atoms. In the third Mg site, Mg(3) is bonded in a 1-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), 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), and two equivalent W(1) atoms. Ce(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Mg(2), four equivalent Mg(1), and two equivalent W(1) atoms. W(1) is bonded in a 12-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Ce(1) atoms. is represented by the CIF file [CIF]
