Novel All-Nitrogen Molecular Crystals Composed of Tetragonal N4 Molecules

“…There is currently much interest in studying all-nitrogen molecules motivated by their considerable potential for applications as high-energy density materials (HEDMs). While ongoing theoretical publications predicted many species of all-nitrogen molecules and ions as possible HEDMs, such as N , N , N , N , N , N , N and even N , only a handful of these were synthesized and experimentally detected [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. There is still a lack of a suitable universal method for the synthesis of all-nitrogen compounds because of their high endothermicity.…”
