Bis(3,3‐dinitroazetidin‐1‐yl)methane (BDNAZM) was synthesized and the crystal structure was determined by a X‐ray diffraction. It belongs to monoclinic system with space group P 2 1 / n . Its thermal behavior and non‐isothermal decomposition kinetics were studied with DSC and TG/DTG methods. The self‐accelerating decomposition temperature ( T SADT ), thermal ignition temperature ( T TIT ), and critical temperature of thermal explosion ( T b ) are 141.06 °C, 154.15 °C and 160.62 °C, respectively. BDNAZM has a low melting point (86.82 °C), and it has higher detonation velocity (7217 ms −1 ) and detonation pressure (22.0 GPa) than these of TNT.
