The material structure described by Mg6CeSi crystallizes in the orthorhombic Amm2 space group. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 1-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and one Si(1) atom. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to one Mg(3), one Mg(4), two equivalent Mg(1), two equivalent Mg(2), two equivalent Ce(1), and two equivalent Si(1) atoms. In the third Mg site, Mg(3) is bonded in a 10-coordinate geometry to two equivalent Mg(2), two equivalent Mg(4), four equivalent Mg(1), and two equivalent Ce(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 Si(1) atoms. Ce(1) is bonded in a 2-coordinate geometry to two equivalent Mg(3), four equivalent Mg(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), four equivalent Mg(2), and two equivalent Ce(1) atoms. is represented by the CIF card [CIF]
