The compound described by (ZnPO4)2N2 crystallizes in the monoclinic P2_1 space group. The structure consists of four ammonia atoms inside a ZnPO4 framework. In the ZnPO4 framework, there are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share  a cornercorner with one P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. In the second Zn site, Zn(2) is bonded to one O(5), one O(6), one O(7), and one O(8) atom to form ZnO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra and corners with three equivalent P(1)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(2), one O(6), one O(7), and one O(8) atom to form PO4 tetrahedra that share  a cornercorner with one Zn(1)O4 tetrahedra and corners with three equivalent Zn(2)O4 tetrahedra. In the second P site, P(2) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one Zn(2)O4 tetrahedra and corners with three equivalent Zn(1)O4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Zn(2) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Zn(2) and one P(1) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Zn(2) and one P(1) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Zn(2) and one P(1) atom. is represented by the CIF file [CIF]
