The material described by Mg6CeNi 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 two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), two equivalent Ce(1), and one Ni(1) atom. 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 Ni(1) atoms. In the third Mg site, Mg(3) is bonded in a 11-coordinate geometry to one Mg(4), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Ce(1), and two equivalent Ni(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), four equivalent Mg(1), and two equivalent Ce(1) atoms. Ce(1) is bonded in a 2-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), four equivalent Mg(3), and two equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), four equivalent Mg(3), and two equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
