KPNH3O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted KO6 octahedra that share corners with six equivalent P(1)NO3 tetrahedra and faces with two equivalent K(1)O6 octahedra. P(1) is bonded to one N(1), one O(1), one O(2), and one O(3) atom to form PNO3 tetrahedra that share corners with six equivalent K(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-56°. N(1) is bonded in a distorted tetrahedral geometry to one P(1), one H(1), one H(2), and one H(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom.
