The structure described by (K2(PO4)3)2N2 crystallizes in the tetragonal I-42d space group. The structure consists of four ammonia atoms inside a K2(PO4)3 framework. In the K2(PO4)3 framework, K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second P site, P(2) is bonded in a tetrahedral geometry to four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one K(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(2) atom. is represented by the CIF file [CIF]
