(LiSO4)2N2 crystallizes in the monoclinic P2_1 space group. The structure consists of four ammonia atoms inside a LiSO4 framework. In the LiSO4 framework, there are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(2), one O(5), one O(7), and one O(8) atom to form LiO4 tetrahedra that share  a cornercorner with one S(1)O4 tetrahedra and corners with three equivalent S(2)O4 tetrahedra.
