- Abstract
Sodium tetrazolate and sodium 5-chlorotetrazolate crystals obtained by recrystallization centred on sodium ion, and the sodium ion was coordinated by tetrazolate rings and crystal water; the packing arrangements of sodium tetrazolate and sodium 5-chlorotetrazolate were rhombus structure which lead to highest thermostability and intersecting channel structure viewed along b axis, respectively; there was a gap between molecules and larger space viewed along a axis of sodium 5-chlorotetrazolate crystal drawing which can coordinate with nitrogen-rich groups and metal ion. The results of thermodynamics calculation indicated that the activation energy of sodium tetrazolate was about 200 kJ•mol-1, sodium 5-chlorotetrazolate was 260-270 kJ•mol-1 which was higher than sodium tetrazolate, however, the decomposition temperature of sodium 5-chlorotetrazolate (241 °C) was lower than sodium tetrazolate (320 °C) which can be explained that the pre-exponential factor (lgA) of sodium 5-chlorotetrazolate (27.8) was greater than that of sodium tetrazolate (18.2), in other words, sodium 5-chlorotetrazolate had more active sites.
