The crystal structure described by RbCdH2OI3 crystallizes in the monoclinic Cc space group. Rb(1) is bonded in a 2-coordinate geometry to two equivalent O(1), one I(1), one I(2), and three equivalent I(3) atoms. Cd(1) is bonded to one I(1), one I(3), and two equivalent I(2) atoms to form corner-sharing CdI4 tetrahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a water-like geometry to two equivalent Rb(1), one H(1), and one H(2) atom. There are three inequivalent I sites. In the first I site, I(1) is bonded in a 2-coordinate geometry to one Rb(1) and one Cd(1) atom. In the second I site, I(2) is bonded in a distorted water-like geometry to one Rb(1) and two equivalent Cd(1) atoms. In the third I site, I(3) is bonded in a 4-coordinate geometry to three equivalent Rb(1) and one Cd(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
