An analysis of the available experimental data on the slow and explosive decomposition of metal azides demonstrates that the intermediate product of the reaction is N6. Based on quantum-chemical calculations, the most symmetrical stable N6 complexes with cyclic, linear, and previously undetected octahedral configurations are established. The energy balance of reactions is calculated. It is demonstrated that the activation energy of forming the cyclic complex is minimum, and the energy of forming the octahedral complex is maximum. Conditions of forming complexes inside the crystal matrix are discussed. An important role of metal in the formation of complexes from azide groups is demonstrated, in particular, the existence of the stable Me2N6 cluster is established. |
