KPNHO2 crystallizes in the trigonal R-3 space group. K(1) is bonded in a 9-coordinate geometry to one N(1), one H(1), three equivalent O(1), and four equivalent O(2) atoms. P(1) is bonded to two equivalent N(1), one O(1), and one O(2) atom to form corner-sharing PN2O2 tetrahedra. N(1) is bonded in a 3-coordinate geometry to one K(1), two equivalent P(1), and one H(1) atom. H(1) is bonded in a single-bond geometry to one K(1) and one N(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent K(1) and one P(1) atom.
