metal–organic framework based, high-energy-density compound,
[Co<sub>5</sub>(3-atrz)<sub>7</sub>(N<sub>3</sub>)<sub>3</sub>] (3-atrz
= 3-amine-1<i>H</i>-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.
