(Ce(SO4)2)2N2 crystallizes in the monoclinic P2_1/m space group. The structure consists of two ammonia atoms inside a Ce(SO4)2 framework. In the Ce(SO4)2 framework, Ce(1) is bonded in a 9-coordinate geometry to one O(3), one O(4), one O(5), two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a tetrahedral geometry to one O(3), one O(4), and two equivalent O(2) atoms. In the second S site, S(2) is bonded in a tetrahedral geometry to one O(1), one O(5), and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Ce(1) and one S(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one S(1) atom. In the third O site, O(3) is bonded in a linear geometry to one Ce(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Ce(1) and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted linear geometry to one Ce(1) and one S(2) atom. In the sixth O site, O(6) is bonded in a water-like geometry to one Ce(1) and one S(2) atom.
