The material structure described by MgSn2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 8-coordinate geometry to three equivalent Sn(1) and five equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to three equivalent Mg(1), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to five equivalent Mg(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
