The material structure described by Rb3Au3I8 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 I(1), one I(2), two equivalent I(3), and three equivalent I(4) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to two equivalent I(1), two equivalent I(2), and two equivalent I(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 I(3) and two equivalent I(4) atoms. In the second Au site, Au(2) is bonded in a linear geometry to one I(1) and one I(2) atom. There are four inequivalent I sites. In the first I site, I(3) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one Au(1) atom. In the second I site, I(4) is bonded in a 5-coordinate geometry to one Rb(2), three equivalent Rb(1), and one Au(1) atom. In the third I site, I(1) is bonded in a trigonal non-coplanar geometry to one Rb(1), one Rb(2), and one Au(2) atom. In the fourth I site, I(2) is bonded in a distorted trigonal non-coplanar geometry to one Rb(1), one Rb(2), and one Au(2) atom. is represented by the CIF card [CIF]
