The crystal structure described by SrMg crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and four equivalent Mg(3) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Mg(2) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to two equivalent Sr(1), two equivalent Sr(2), and four equivalent Sr(3) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Sr(3), four equivalent Sr(2), and two equivalent Mg(3) atoms. In the third Mg site, Mg(3) is bonded in a body-centered cubic geometry to two equivalent Sr(3), four equivalent Sr(1), and two equivalent Mg(2) atoms. is represented by the CIF file [CIF]
