The crystal structure described by Au3Br crystallizes in the hexagonal P6_3/mmc space group. Au(1) is bonded in a 8-coordinate geometry to six equivalent Au(1) and two equivalent Br(1) atoms. Br(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. is represented by the CIF card [CIF]
