Be2Ta is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Be(1) is bonded to six equivalent Be(1) and six equivalent Ta(1) atoms to form a mixture of face, corner, and edge-sharing BeTa6Be6 cuboctahedra. Ta(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ta(1) atoms.
