The low temperature crystal packing of (TSeT) 2Cl is similar to that obtained at room temperature, no structural transition occuring. Only small changes in the atomic parameters are observed. On the contrary, the high pressure and the high pressure-low temperature crystal structures show a change in the symmetry which leads to a difference in the network of the chloride anions and in their environment.
