The material described by SrMg6Ce crystallizes in the orthorhombic Amm2 space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Ce(1) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Mg(1), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Ce(1) atoms. In the third Mg site, Mg(3) is bonded in a distorted q6 geometry to four equivalent Mg(1), four equivalent Mg(2), and two equivalent Ce(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 8-coordinate geometry to two equivalent Sr(1), four equivalent Mg(1), and four equivalent Mg(2) atoms. Ce(1) is bonded in a 10-coordinate geometry to two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms. is represented by the CIF card [CIF]
