MgSn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Sn(1) atoms to form MgSn12 cuboctahedra that share corners with twelve equivalent Mg(1)Sn12 cuboctahedra, edges with twenty-four equivalent Sn(1)Mg4Sn8 cuboctahedra, faces with six equivalent Mg(1)Sn12 cuboctahedra, and faces with twelve equivalent Sn(1)Mg4Sn8 cuboctahedra. Sn(1) is bonded to four equivalent Mg(1) and eight equivalent Sn(1) atoms to form distorted SnMg4Sn8 cuboctahedra that share corners with twelve equivalent Sn(1)Mg4Sn8 cuboctahedra, edges with eight equivalent Mg(1)Sn12 cuboctahedra, edges with sixteen equivalent Sn(1)Mg4Sn8 cuboctahedra, faces with four equivalent Mg(1)Sn12 cuboctahedra, and faces with fourteen equivalent Sn(1)Mg4Sn8 cuboctahedra.
