摘　　要：A new crystal form of diammonium 5,5＇-bistetrazole-1,1＇-diolate （1） was prepared by two novel methods and fully characterized by using IR, NMR spectroscopy, elementary analysis, single crystal X-ray crystallography and thermal gravity/differential thermal analysis （TG/DTA）. Crystalline 1 was found as monoclinic and space group of P21/c （14）. The TG/DTA analysis showed that the decomposition temperature of 1 was 287.8℃ with a mass loss of 91.2% in the range of 220-300℃ at a heating rate of 5℃/min. The sensitivities test towards impact, friction of 1 indicated that 1 has much lower sensitivities than those of RDX/HMX and is comparable to those of TNT, which suggested that 1 could be used as a good candidate of new insensitive energetic compound.A new crystal form of diammonium 5,5＇-bistetrazole-1,1＇-diolate （1） was prepared by two novel methods and fully characterized by using IR, NMR spectroscopy, elementary analysis, single crystal X-ray crystallography and thermal gravity/differential thermal analysis （TG/DTA）.
