The crystal structure described by NH2O2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydroxyazanium;nitric acid molecules. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one O(2), one O(3), and one O(4) atom. In the second N site, N(2) is bonded in a tetrahedral geometry to one H(2), one H(3), one H(4), and one O(1) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) and one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(2) atom. There are four inequivalent O sites. In the first O site, O(3) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. In the second O site, O(4) is bonded in a single-bond geometry to one N(1) atom. In the third O site, O(1) is bonded in a water-like geometry to one N(2) and one H(1) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one N(1) atom. is represented by the CIF file [CIF]
