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.
