Mg4SnGe crystallizes in the cubic F-43m space group. Mg(1) is bonded to six equivalent Mg(1), three equivalent Sn(1), and three equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing MgMg6Sn3Ge3 cuboctahedra. Sn(1) is bonded in a 12-coordinate geometry to twelve equivalent Mg(1) atoms. Ge(1) is bonded in a 12-coordinate geometry to twelve equivalent Mg(1) atoms.
