[Formula see text] is the first successfully synthesized salt that has a polymeric nitrogen moeity ([Formula see text]). Although 12 other [Formula see text] salts followed, with [Formula see text] and [Formula see text] being the most stable, the crystal structure of [Formula see text] remains unknown. Currently, it is impossible to experimentally determine the structures of [Formula see text] due to its marginal stability and explosive nature. Here, following an ab initio evolutionary prediction and using only the stoichiometry of
