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.
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 shorter (3.17 Å) and one longer (3.39 Å) Mg(1)-Sn(1) bond length. There are a spread of Mg(1)-Sn(2) bond distances ranging from 3.07-3.21 Å. 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. Both Sn(1)-Sn(2) bond lengths are 3.29 Å. There is one shorter (3.09 Å) and two longer (3.23 Å) Sn(1)-Sn(1) bond lengths. 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.
