The structure described by CsH2PO4 crystallizes in the monoclinic P2_1 space group. Cs(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), and one O(4) atom. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. 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 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 bent 120 degrees geometry to one Cs(1), one P(1), and one H(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cs(1), one P(1), and one H(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cs(1), one P(1), and one H(2) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Cs(1), one P(1), and one H(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
