Therefore, in order to obtain an explosive with performance close to DAP-4, lower sensitivity and cost than DAP-4, and a structure similar to DAP-4, a novel analogical molecular perovskite energetic material, NP-1, was synthesized via a common reaction between an acid and an amine. The single-crystal diffraction results indicate that the molecular formula of NP-1 is C<sub>14<\/sub>H<sub>31<\/sub>N<sub>4<\/sub>O<sub>12<\/sub>Cl<sub>3<\/sub> or [(C<sub>14<\/sub>H<sub>31<\/sub>N<sub>4<\/sub>)(ClO<sub>4<\/sub>)<sub>3<\/sub>]. NP-1 belongs to the orthorhombic crystal system and Pnma space group; each unit cell contains eight C<sub>14<\/sub>N<sub>4<\/sub>H<sub>34<\/sub>, six guest water molecules and twenty-four perchlorate ions (ClO<sub>4<\/sub><sup>&#8211;<\/sup>). The unit cell parameters are a=25.154(2) \u00c5, b=9.5094(8) \u00c5, c=19.7867(14) \u00c5, and \u03b1=\u03b2=\u03b3=90\u00b0. The results of XRD analysis and mass spectrometry analysis verified the finds from single crystal diffraction analysis. DSC analysis indicates that the thermal decomposition temperature of NP-1 is 211<sup>o<\/sup>C, and the activation energy for thermal decomposition of NP-1 is 241.6 kJ\/mol. NP-1 has the characteristics of low sensitivity, easy availability of raw materials, simple preparation process, and low cost. Thus, NP-1 is more suitable for large-scale production during emergencies to compensate for the shortage of main explosives than the molecular perovskite energetic material DAP-4.<\/p>\n<hr \/>\n<p>Ref: JPyro 2025 (80-88)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Xiaolan SONG, Yi WANG, Chongwei AN, Fengsheng LI Abstract: Molecular perovskite energetic material DAP-4, i.e. (H2dabco)[NH4(ClO4)3], is a very excellent explosive, but its friction sensitivity is too high and the raw materials are slightly expensive.
