This structure was solved as a high symmetry model (Imm2), which leads
to the solution of an quarter of molecule as an independent structure. The
high symmetry gives rise to the difficultes of addition of hydrogen atoms to
Et4N+ cation in this model. Therefore, its hydrogen atoms were not
added, but they were included in the reported formula.
