NH3SO4 is High Pressure (4-7GPa) Tellurium structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four NH3SO4 clusters. N(1) is bonded to one H(1), one H(2), one H(3), and one O(3) atom to form distorted NH3O tetrahedra that share  a cornercorner with one S(1)O4 tetrahedra. 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. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share  a cornercorner with one N(1)H3O tetrahedra. There are four inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one S(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to one S(1) atom. In the third O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the fourth O site, O(3) is bonded in a bent 120 degrees geometry to one N(1) and one S(1) atom.
