The structure described by AuTl2 is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Au(1) is bonded in a 10-coordinate geometry to two equivalent Au(1) and eight equivalent Tl(1) atoms. Tl(1) is bonded in a 4-coordinate geometry to four equivalent Au(1) atoms. is represented by the CIF file [CIF]
