(K(PO4)2)2N2 crystallizes in the tetragonal I-4 space group. The structure consists of two ammonia atoms inside a K(PO4)2 framework. In the K(PO4)2 framework, K(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. In the second P site, P(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two 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(2) atom.
