The crystal structure described by RbH3O2 crystallizes in the orthorhombic Cmc2_1 space group. Rb(1) is bonded in a 16-coordinate geometry to four equivalent H(1), six equivalent H(2), two equivalent O(2), and four equivalent O(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to four equivalent Rb(1) and one O(2) atom. In the second H site, H(2) is bonded in a distorted linear geometry to three equivalent Rb(1), one O(1), and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to four equivalent Rb(1) and two equivalent H(2) atoms. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Rb(1), one H(1), and two equivalent H(2) atoms. is represented by the CIF card [CIF]
