| Abstract: | Metal–organic framework (MOF)‐based energetic material [Cu3(MA)2(N3)3] ( 1 ; MA=melamine) was synthesized and structurally characterized (47.55 % N). The structural analysis revealed the existence of unusual multiwalled tubular channels and interweaving of single and double helical units in 1 . The standard molar enthalpy of formation was found to be 1788.73 kJ mol?1, which is the highest value among previously reported MOF‐based energetic materials. The calculated detonation properties showed that 1 can be used as a potential explosive. Sensitivity tests revealed that 1 is insensitive and thus can function as a high‐energy‐density material with a favorable level of safety. |
