The crystal structure described by MgSn crystallizes in the monoclinic Cm space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to one Sn(2), two equivalent Sn(1), and three equivalent Sn(3) atoms. In the second Mg site, Mg(2) is bonded in a 7-coordinate geometry to two equivalent Sn(2), two equivalent Sn(3), and three equivalent Sn(1) atoms. In the third Mg site, Mg(3) is bonded in a 7-coordinate geometry to two equivalent Sn(1), two equivalent Sn(3), and three equivalent Sn(2) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 7-coordinate geometry to two equivalent Mg(1), two equivalent Mg(3), and three equivalent Mg(2) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to one Mg(1), two equivalent Mg(2), and three equivalent Mg(3) atoms. In the third Sn site, Sn(3) is bonded in a 7-coordinate geometry to two equivalent Mg(2), two equivalent Mg(3), and three equivalent Mg(1) atoms. is represented by the CIF file [CIF]
