The crystal structure described by RbHSeO4 crystallizes in the orthorhombic P2_12_12_1 space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent O(1), two equivalent O(3), two equivalent O(4), and three equivalent O(2) atoms. H(1) is bonded in a linear geometry to one O(3) and one O(4) atom. Se(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one Se(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one H(1), and one Se(1) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one H(1), and one Se(1) atom. is represented by the CIF card [CIF]
