The compound described by RbH2PO4 crystallizes in the monoclinic P2_1/m space group. Rb(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. In the second H site, H(2) is bonded in a linear geometry to two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one P(1), and one H(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Rb(1), one P(1), and one H(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one P(1), and one H(2) atom. is represented by the CIF card [CIF]
