The structure described by (FeP2(HO4)2)6N2(NH4)4 crystallizes in the triclinic P-1 space group. The structure consists of one ammonia atom and two ammonium molecules inside a FeP2(HO4)2 framework. In the FeP2(HO4)2 framework, there are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(10), one O(2), one O(5), one O(8), and one O(9) atom to form FeO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. In the second Fe site, Fe(2) is bonded to two equivalent O(4), two equivalent O(6), and two equivalent O(7) atoms to form FeO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(4), one O(5), and one O(9) atom to form PO4 tetrahedra that share  a cornercorner with one Fe(2)O6 octahedra and corners with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-48°. In the second P site, P(2) is bonded to one O(1), one O(10), one O(11), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one Fe(2)O6 octahedra and corners with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-50°. In the third P site, P(3) is bonded to one O(12), one O(2), one O(6), and one O(8) atom to form PO4 tetrahedra that share  a cornercorner with one Fe(2)O6 octahedra and corners with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-52°. There are three inequivalent H sites. In the first H site, H(5) is bonded in a distorted single-bond geometry to one O(10) and one O(12) atom. In the second H site, H(6) is bonded in a single-bond geometry to one O(3) atom. In the third H site, H(7) is bonded in a single-bond geometry to one O(11) atom. There are twelve inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Fe(1) and one P(3) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one P(1) and one H(6) atom. In the fourth O site, O(4) is bonded in a linear geometry to one Fe(2) and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Fe(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Fe(2) and one P(3) atom. In the seventh O site, O(7) is bonded in a distorted bent 120 degrees geometry to one Fe(2) and one P(2) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Fe(1) and one P(3) atom. In the ninth O site, O(9) is bonded in a 2-coordinate geometry to one Fe(1) and one P(1) atom. In the tenth O site, O(10) is bonded in a 3-coordinate geometry to one Fe(1), one P(2), and one H(5) atom. In the eleventh O site, O(11) is bonded in a water-like geometry to one P(2) and one H(7) atom.
