Fe3H6(SO7)2NH4 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three ammonium molecules and three Fe3H6(SO7)2 sheets oriented in the (0, 0, 1) direction. In each Fe3H6(SO7)2 sheet, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four equivalent FeO6 octahedra and corners with two SO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–46°. There are a spread of Fe–O bond distances ranging from 2.02–2.09 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are two inequivalent S2+ sites. In the first S2+ site, S2+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There is one shorter (1.47 Å) and three longer (1.50 Å) S–O bond length. In the second S2+ site, S2+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent FeO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There is one shorter (1.47 Å) and three longer (1.50 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe3+ and one S2+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Fe3+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Fe3+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe3+ and one S2+ atom.
