description: Zn2Ga2P4NH4O16NH4 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of two ammonium molecules and one Zn2Ga2P4NH4O16 framework. In the Zn2Ga2P4NH4O16 framework, there are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–1.99 Å. In the second Zn2+ site, Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.93–1.96 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to one N3- and four O2- atoms to form GaNO4 trigonal bipyramids that share corners with four PO4 tetrahedra. The Ga–N bond length is 2.04 Å. There are a spread of Ga–O bond distances ranging from 1.86–2.07 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form GaO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.84–1.87 Å. There are four 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 GaO4 tetrahedra, corners with two equivalent ZnO4 tetrahedra, and a cornercorner with one GaNO4 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two ZnO4 tetrahedra and corners with two equivalent GaNO4 trigonal bipyramids.

In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two ZnO4 tetrahedra and corners with two equivalent GaO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one GaO4 tetrahedra, corners with two equivalent ZnO4 tetrahedra, and a cornercorner with one GaNO4 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. N3- is bonded in a distorted trigonal non-coplanar geometry to one Ga3+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. 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. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are sixteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Ga3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ga3+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ga3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Ga3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ga3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Ga3+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ga3+ and one P5+ atom. In the fifteenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Ga3+ and one P5+ atom. In the sixteenth O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one P5+ atom.
