Rb2Au3AgI8 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 10-coordinate geometry to two equivalent I(1), two equivalent I(3), three equivalent I(2), and three equivalent I(4) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted linear geometry to one I(1), one I(3), and one I(4) atom. In the second Au site, Au(2) is bonded in a square co-planar geometry to two equivalent I(2) and two equivalent I(4) atoms. Ag(1) is bonded in a tetrahedral geometry to two equivalent I(1) and two equivalent I(3) atoms. There are four inequivalent I sites. In the first I site, I(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Rb(1), one Au(1), and one Ag(1) atom. In the second I site, I(2) is bonded in a rectangular see-saw-like geometry to three equivalent Rb(1) and one Au(2) atom. In the third I site, I(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Au(1), and one Ag(1) atom. In the fourth I site, I(4) is bonded in a 5-coordinate geometry to three equivalent Rb(1), one Au(1), and one Au(2) atom.
