The material described by Mg2Sr crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(4), and four equivalent Mg(3) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent Mg(3), two equivalent Mg(4), and four equivalent Mg(2) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to two equivalent Sr(1), two equivalent Mg(2), and four equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to four equivalent Sr(2), two equivalent Mg(1), and two equivalent Mg(4) atoms. In the third Mg site, Mg(3) is bonded in a 6-coordinate geometry to two equivalent Sr(2) and four equivalent Sr(1) atoms. In the fourth Mg site, Mg(4) is bonded in a 10-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), two equivalent Mg(2), and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
