Be4FeGe is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Be(1) is bonded to six equivalent Be(1), three equivalent Fe(1), and three equivalent Ge(1) atoms to form a mixture of corner, face, and edge-sharing BeBe6Fe3Ge3 cuboctahedra. Fe(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Fe(1) atoms.
