The material described by (VZn2(PO4)4)2(N2)3 crystallizes in the monoclinic C2/c space group. The structure consists of twelve ammonia atoms inside a VZn2(PO4)4 framework. In the VZn2(PO4)4 framework, V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. Zn(1) is bonded to one O(4), one O(5), one O(6), and one O(7) 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(1), one O(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one V(1)O6 octahedra and corners with three equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(7), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent V(1)O6 octahedra and  a cornercorner with one Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 34-40°. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a distorted bent 150 degrees geometry to one Zn(1) and one P(2) atom. In the second O site, O(8) is bonded in a single-bond geometry to one P(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one P(1) atom. In the fourth O site, O(2) is bonded in a bent 150 degrees geometry to one V(1) and one P(2) atom. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one P(2) atom. In the sixth O site, O(4) is bonded in a bent 120 degrees geometry to one Zn(1) and one P(1) atom. In the seventh O site, O(5) is bonded in a bent 120 degrees geometry to one Zn(1) and one P(1) atom. In the eighth O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one P(1) atom. is represented by the CIF card [CIF]
