- 2The increase in NN bond energies (NN: 40 kcal mol−1; NN: 100 kcal mol−1; NN: 225 kcal mol−1) with a higher bond order favors the disproportion and forming of multiple bonds (bond energies are taken from Inorganic Chemistry, HarperCollins, New York, 1993.), , ,

- 11Covalent azides can decompose explosively and unexpectedly under various conditions. They should be handled only in very small scales and with appropriate safety equipment (thick leather or Kevlar gloves, face shield and protective clothing as leather jackets) and with methods and techniques appropriate to explosives.
- 20For example, a theoretical study[20a] predicted the homoleptic azides [M(N3)4] (M=Ti, Zr, Hf) of Group 4 ([Ti(N3)4] was prepared recently)[20b] to be stable with respect to the formation of M and 6 N2, whereas the isomers with the formula (N5)[MN7] will not be stable.[20c]
- 21Evidence for N5− coordinated to Zn2+ in solution has been given based on 15N NMR spectroscopy,[21a] and computational evidence implies that the gas-phase stability of some pentazolides were equal to or higher than the stability of the experimentally known phenypentazole.[21b]
