The compound described by Mg2Sr crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 13-coordinate geometry to five equivalent Sr(1), three equivalent Mg(1), and five equivalent Mg(2) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 9-coordinate geometry to three equivalent Sr(1), two equivalent Mg(1), and four equivalent Mg(2) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to five equivalent Sr(1) and four equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
