The compound described by MgSn2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded to ten equivalent Sn(1) atoms to form a mixture of distorted face and edge-sharing MgSn10 cuboctahedra. Sn(1) is bonded to five equivalent Mg(1) atoms to form a mixture of distorted corner, face, and edge-sharing SnMg5 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
