The structure described by Sr(PO3)4N2 crystallizes in the tetragonal I-4 space group. The structure consists of four ammonia atoms inside a Sr(PO3)4 framework. In the Sr(PO3)4 framework, Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form corner-sharing PO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Sr(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
