(Al4P5HO20)2(N2)2O2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of four ammonia molecules, two water molecules, and one Al4P5HO20 framework. In the Al4P5HO20 framework, there are four inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four PO4 tetrahedra. There is three shorter (1.75 Å) and one longer (1.77 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded to five O2- atoms to form AlO5 trigonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.79–1.93 Å. In the third Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.87–1.92 Å. In the fourth Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.74–1.77 Å. There are five inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one AlO6 octahedra and corners with three AlO4 tetrahedra. The corner-sharing octahedral tilt angles are 28°. There are a spread of P–O bond distances ranging from 1.52–1.55 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent AlO6 octahedra, a cornercorner with one AlO4 tetrahedra, and a cornercorner with one AlO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 16–34°. There are a spread of P–O bond distances ranging from 1.53–1.55 Å.

The corner-sharing octahedral tilt angles are 35°. There are a spread of P–O bond distances ranging from 1.53–1.55 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three AlO4 tetrahedra and a cornercorner with one AlO5 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.52–1.55 Å. In the fifth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent AlO6 octahedra and a cornercorner with one AlO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 28–41°. There are a spread of P–O bond distances ranging from 1.52–1.60 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are twenty inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a linear geometry to one Al3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+ and one P5+ atom.
