View morePure nitrogen can be considered as a material with optimized storage of chemical energy because of the huge difference in energy between triply bonded di-nitrogen and singly bonded nitrogen. N ≡ N bond is one of the strongest chemical bonds known, containing 4.94eV atom −1 while the N-N bond is much weaker with −0.83eV atom −1 .
Or, in other words, this chemical energy can be ideally stored by transforming a triple bond into three single bonds. Thus, nitrogen may form a high-energy density material with energy content higher than that of any known nonnuclear material. The greatest utility of fully single-bonded nitrogen would be as high explosives.
By Zintl–Klemm theory 36 and calculating the electronic localization function, 37 we know that the bonding manner of nitrogen atoms for P -SrN 6 in high pressure is nitrogen–nitrogen single bond and double bonds and C 2/ m -BaN 6 in high pressure the bonding manner of nitrogen atoms is nitrogen–nitrogen single bond.
We calculated the bond length between nitrogen and nitrogen in the C2/m-BaN6 structure and found that the bond length between nitrogen and nitrogen in the N6 ring network structure is between 1.37–1.40 ̊A. Because this values are close to the bond length of the nitrogennitrogen single bond,18 which indicates
trons. By analyzing the ELF of C2/m-BaN6 structure, we can conclude that the degree of N atoms polymerization in C2/m-BaN6 is relatively higher than other polynitrogen structures, so it has higher energy densities. Therefore, it also can be judged that nitrogennitrogen single bond is formed between nitrogen and nitrogen.
