The material described by NH4NO3 is Indium-like structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four NH4NO3 clusters. There are two inequivalent N sites. In the first N site, N(1) is bonded in a water-like geometry to one N(2) and two equivalent H(1) atoms. In the second N site, N(2) is bonded in a 4-coordinate geometry to one N(1), one O(1), and two equivalent O(2) atoms. There are two 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 O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one N(2) atom. In the second O site, O(2) is bonded in a water-like geometry to one N(2) and one H(2) atom. is represented by the CIF card [CIF]
