The compound described by (Ce(PO4)2)2(N2)2O2 crystallizes in the tetragonal I4_1/amd space group. The structure consists of eight ammonia atoms and four water atoms inside a Ce(PO4)2 framework. In the Ce(PO4)2 framework, Ce(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(3) atoms. There are two inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one Ce(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ce(1) and one P(1) atom. is represented by the CIF file [CIF]
