High-Performance Energetic Characteristics and Magnetic Properties of a Three-Dimensional Cobalt(II) Metal–Organic Framework Assembled with Azido and Triazole

A three-dimensional metal–organic framework based, high-energy-density compound, [Co₅(3-atrz)₇(N₃)₃] (3-atrz = 3-amine-1H-1,2,4-triazole), features superior detonation properties, insensitivity, and thermostability. Magnetic studies show that the compound characterizes the coexistence of remarkable coercivity, metamagnetism, long-range ordering, and relaxation dynamics. The heat-capacity measurement confirms the typical long-range antiferromagnetic ordering below 16 K. This difunctional system exemplifies an effective attempt at developing advanced magnetoenergetic materials.
