The material structure described by Rb3Au3Br8 crystallizes in the monoclinic C2/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 7-coordinate geometry to one Br(1), one Br(2), two equivalent Br(3), and three equivalent Br(4) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent Br(1), two equivalent Br(2), and two equivalent Br(4) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a square co-planar geometry to two equivalent Br(3) and two equivalent Br(4) atoms. In the second Au site, Au(2) is bonded in a distorted linear geometry to one Br(1), one Br(2), one Br(3), and one Br(4) atom. There are four inequivalent Br sites. In the first Br site, Br(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Au(1), and one Au(2) atom. In the second Br site, Br(4) is bonded in a 6-coordinate geometry to one Rb(2), three equivalent Rb(1), one Au(1), and one Au(2) atom. In the third Br site, Br(1) is bonded in a distorted trigonal non-coplanar geometry to one Rb(1), one Rb(2), and one Au(2) atom. In the fourth Br site, Br(2) is bonded in a 3-coordinate geometry to one Rb(1), one Rb(2), and one Au(2) atom. is represented by the CIF card [CIF]
