A new energetic MOF, [Cu₂(to)(dns)(H₂O)]_n (1; H₂to = 1,2,4-triazol-5-one, H₂dns = 3,5-dinitrosalicylic acid), has been synthesized and structurally characterized. Single-crystal X-ray diffraction analysis revealed that 1 possesses a compact 3D architecture. Noteworthy, the two oxygen atoms of one nitro coordinate to two Cu^II ions in a syn-anti mode, which decreases its sensitivity but has no influence on its explosive properties. Based on the results of thermogravimetric and differential scanning calorimetry analyses, MOF 1 displays a rapid thermal decomposition process and superior thermostability. The non-isothermal kinetics of the exothermic process of 1 were studied by the methods of Kissinger and Ozawa. The sensitivity tests and calculated detonation properties show that 1 has the potential to be used in green explosives.
