Be4CoGe 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 Co(1), and three equivalent Ge(1) atoms to form a mixture of edge, corner, and face-sharing BeBe6Co3Ge3 cuboctahedra. Co(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 Co(1) atoms.
