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.
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 shorter (3.20 Å) and two longer (3.21 Å) Mg(1)-Sn(1) bond lengths. There are four shorter (3.38 Å) and two longer (3.39 Å) Mg(1)-Sn(2) bond lengths. 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. There are two shorter (3.30 Å) and four longer (3.46 Å) Sn(1)-Sn(2) bond lengths. 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. There are four shorter (3.21 Å) and two longer (3.38 Å) Sn(2)-Sn(2) bond lengths.
