(LiS2O5)2N2(CF3)4 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of eight ammonia molecules; sixteen fluoroform molecules; and one LiS2O5 sheet oriented in the (0, 1, 0) direction. In the LiS2O5 sheet, there are six inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.06–2.58 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted edge-sharing LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.00–2.61 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form distorted edge-sharing LiO6 octahedra. There are a spread of Li–O bond distances ranging from 1.91–2.62 Å. In the fourth Li1+ site, Li1+ is bonded in a distorted octahedral geometry to six O2- atoms.
