The material structure described by SrMg6C crystallizes in the orthorhombic Amm2 space group. Sr(1) is bonded in a 14-coordinate geometry to two equivalent Sr(1), two equivalent Mg(1), two equivalent Mg(2), four equivalent Mg(3), and four equivalent Mg(4) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a water-like geometry to one Sr(1), two equivalent Mg(4), and two equivalent C(1) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Mg(4), and four equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a single-bond geometry to two equivalent Sr(1), two equivalent Mg(2), and one C(1) atom. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to four equivalent Sr(1), two equivalent Mg(2), and four equivalent Mg(1) atoms. C(1) is bonded in a 6-coordinate geometry to two equivalent Mg(3) and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
