“…Particularly nitrogen rich examples are the metal or semimetal hexaazides [M n (N 3 ) 6 ] ( n ‑6)‑ , where n is the oxidation state of the central atom, mostly from the group of Christe. These have been prepared for Mn IV , In III , Tl III , Si IV , Ge IV , As V , − Sb V , , Se IV , Ti IV , V IV , Nb V , Ta V , Mo VI , W VI , Te IV , and Bi III . , Only two examples of heptaazides are known, both from the group of Christe: [Mo VI (N 3 ) 7 ] − and [W VI (N 3 ) 7 ] − .…”

The properties of catenated nitrogen molecules, molecules containing internal chains of bonded nitrogen atoms, is of fundamental scientific interest in chemical structure and bonding, as nitrogen is uniquely situated in the periodic table to form kinetically stable compounds often with chemically stable N–N bonds but which are thermodynamically unstable in that the formation of stable multiply bonded N2 is usually thermodynamically preferable. This unique placement in the periodic table makes catenated nitrogen compounds of interest for development of high-energy-density materials, including explosives for defense and construction purposes, as well as propellants for missile propulsion and for space exploration. This review, designed for a chemical audience, describes foundational subjects, methods, and metrics relevant to the energetic materials community and provides an overview of important classes of catenated nitrogen compounds ranging from theoretical investigation of hypothetical molecules to the practical application of real-world energetic materials. The review is intended to provide detailed chemical insight into the synthesis and decomposition of such materials as well as foundational knowledge of energetic science new to most chemists.

“…Decomposition reactions of the type N → ( /2)N 2 can be exothermic by up to 50 kcal/mol per nitrogen atom (approximately 3.5 kilocalories per gram of material). Experimental synthetic successes in high-energy nitrogen materials include the N 5 + and N 5 − ions [1-4] as well as various azido compounds [5][6][7][8][9] and even a network polymer of nitrogen [10]. Additionally, nitrogenrich salts [11] and the N 7 O + ion [12] have been achieved experimentally.…”

Molecules consisting of nitrogen have been the subject of much attention due to their potential as high-energy materials. Complex molecules consisting entirely of nitrogen can be subject to rapid decomposition, and therefore other atoms are incorporated into the structure to enhance stability. Previous studies have explored the incorporation of carbon atoms into otherwise all-nitrogen cages molecules. The current study involves two such cages, N 10 C 2 and N 16 C 2 , whose structures are derived from N 12 and N 18 , respectively. The N 10 C 2 and N 16 C 2 cages in this study are modified by bonding groups O 3 and CO 3 to determine the effect on the relative energies between the isomers and on the thermodynamic energy release properties. Energetic trends for N 10 C 2 and N 16 C 2 are calculated and discussed.
