The crystal structure described by MgSn crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Mg(3), two equivalent Sn(1), two equivalent Sn(3), and four equivalent Sn(2) atoms. In the third Mg site, Mg(3) is bonded to two equivalent Mg(2), two equivalent Sn(2), and two equivalent Sn(3) atoms to form a mixture of distorted corner and edge-sharing MgMg2Sn4 tetrahedra. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(3), and four equivalent Mg(2) atoms. In the third Sn site, Sn(3) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and two equivalent Mg(3) atoms. is represented by the CIF file [CIF]
