Abstract
An energetic salt, sodium nitroformate (NaNF), was synthesized and characterized by elemental analysis, IR and UV spectra, and its crystal structure was first determined by single crystal X-ray diffraction. The structure exhibits two types of π-π stacking interactions between the nitroformate anions, i e, the parallel-displaced and T-shaped configurations. Furthermore, the thermal decomposition mechanism was investigated by DSC, TG-DTG and FTIR techniques. The kinetic parameters of the thermal decomposition were also calculated by using Kissinger’s and Ozawa-Doyle’s methods. The results show that NaNF has a good thermal stability, which is attributed to the π-π stacking interactions.
