The material structure described by SrMg crystallizes in the monoclinic Cm space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 4-coordinate geometry to two equivalent Sr(3), three equivalent Sr(2), two equivalent Mg(1), and two equivalent Mg(3) atoms. In the second Sr site, Sr(2) is bonded to two equivalent Sr(2), two equivalent Sr(3), three equivalent Sr(1), one Mg(3), two equivalent Mg(1), and two equivalent Mg(2) atoms to form a mixture of distorted face and corner-sharing SrSr7Mg5 cuboctahedra. In the third Sr site, Sr(3) is bonded in a 12-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), two equivalent Sr(3), one Mg(1), two equivalent Mg(3), and three equivalent Mg(2) atoms. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 5-coordinate geometry to one Sr(3), two equivalent Sr(1), two equivalent Sr(2), and two equivalent Mg(2) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to two equivalent Sr(2), three equivalent Sr(3), two equivalent Mg(1), and two equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a 7-coordinate geometry to one Sr(2), two equivalent Sr(1), two equivalent Sr(3), and two equivalent Mg(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
