The material described by RbAu(O3I)4 crystallizes in the monoclinic C2 space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Au(1) is bonded in a rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one Au(1), and one I(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Rb(1), one I(1), and one I(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Rb(1) and one I(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Rb(1) and one I(2) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one I(2) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Au(1) and one I(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. In the second I site, I(2) is bonded in a 4-coordinate geometry to one O(2), one O(4), one O(5), and one O(6) atom. is represented by the CIF file [CIF]
