The material described by (Be2P3O10)2N2 crystallizes in the monoclinic C2/c space group. The structure consists of four ammonia atoms inside a Be2P3O10 framework. In the Be2P3O10 framework, Be(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form BeO4 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(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra and corners with three equivalent Be(1)O4 tetrahedra. In the second P site, P(2) is bonded to two equivalent O(4) and two equivalent O(5) atoms to form PO4 tetrahedra that share corners with two equivalent Be(1)O4 tetrahedra and corners with two equivalent P(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one Be(1) and one P(1) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(5) is bonded in a bent 120 degrees geometry to one Be(1) and one P(2) atom. In the fourth O site, O(1) is bonded in a bent 150 degrees geometry to one Be(1) and one P(1) atom. In the fifth O site, O(2) is bonded in a bent 120 degrees geometry to one Be(1) and one P(1) atom. is represented by the CIF card [CIF]
