The material described by MgSn3 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded in a 10-coordinate geometry to four equivalent Sn(1) and six equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) and six equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 12-coordinate geometry to three equivalent Mg(1), three equivalent Sn(1), and six equivalent Sn(2) atoms. is represented by the CIF file [CIF]
