Be4TiTa 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 Ti(1), and three equivalent Ta(1) atoms to form a mixture of face, corner, and edge-sharing BeTa3Ti3Be6 cuboctahedra. Ti(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ta(1) atoms. Ta(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ti(1) atoms.
