The crystal structure described by AuTl2 crystallizes in the tetragonal I4/mcm space group. Au(1) is bonded to two equivalent Au(1) and four equivalent Tl(1) atoms to form distorted corner-sharing AuTl4Au2 octahedra. The corner-sharing octahedral tilt angles range from 0-43°. Tl(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Au(1) atoms. is represented by the CIF file [CIF]
