The crystal structure described by AuTa3 crystallizes in the cubic Pm-3n space group. Ta(1) is bonded in a 6-coordinate geometry to two equivalent Ta(1) and four equivalent Au(1) atoms. Au(1) is bonded to twelve equivalent Ta(1) atoms to form a mixture of face and edge-sharing AuTa12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
