The material structure described by (ZnAsO4)2N2 crystallizes in the monoclinic P2_1 space group. The structure consists of four ammonia atoms inside a ZnAsO4 framework. In the ZnAsO4 framework, there are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(3), one O(4), one O(5), and one O(7) atom to form ZnO4 tetrahedra that share  a cornercorner with one As(2)O4 tetrahedra and corners with three equivalent As(1)O4 tetrahedra. In the second Zn site, Zn(2) is bonded to one O(1), one O(2), one O(6), and one O(8) atom to form ZnO4 tetrahedra that share  a cornercorner with one As(1)O4 tetrahedra and corners with three equivalent As(2)O4 tetrahedra. There are two inequivalent As sites. In the first As site, As(1) is bonded to one O(3), one O(4), one O(5), and one O(8) atom to form AsO4 tetrahedra that share  a cornercorner with one Zn(2)O4 tetrahedra and corners with three equivalent Zn(1)O4 tetrahedra. In the second As site, As(2) is bonded to one O(1), one O(2), one O(6), and one O(7) atom to form AsO4 tetrahedra that share  a cornercorner with one Zn(1)O4 tetrahedra and corners with three equivalent Zn(2)O4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(2) and one As(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Zn(2) and one As(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one As(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one As(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one As(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to one Zn(2) and one As(2) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Zn(1) and one As(2) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Zn(2) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
