The compound described by KH2PO4 crystallizes in the orthorhombic P2_12_12_1 space group. K(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(3), and two equivalent O(4) atoms. 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 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(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1), one P(1), and one H(1) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one P(1) and one H(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. is represented by the CIF card [CIF]
