A new energetic MOFs, {[Ni 2 (C 2 H 5 N 5 ) 2 (C 3 H 2 O 4 ) 2 (H 2 O)].3H 2 O} n (Hdatrz (C 2 H 5 N 5 )=3,5-diamino-1,2,4-triazole, H 2 mal (C 3 H 4 O 4 )=malonic acid), has been synthesized and characterized by element analysis, chemical analysis, IR spectroscopy, single-crystal X-ray diffraction and thermal analysis. X-ray diffraction analysis confirmed that the compound featured a 2D layer structure with dinuclear Ni(II) unit. Thermal analysis demonstrated that the compound after dehydration have good thermostability with decomposition temperature up to 633K. The non-isothermal kinetics for the compound was studied by Kissinger's and Ozawa's methods. The Arrhenius equation of initial thermal decomposition process of compound can be expressed as lnk=55.89-332.01x10 3 /RT. Furthermore, a reasonable thermochemical cycle was designed based on the preparation reaction of the compound, and standard molar enthalpy of dissolution of reactants and products were measured by RD496-2000 calorimeter. Finally, the standard molar enthalpy of formation of the compound was determined to be -(2766.3+/-2.3)kJ.mol -1 in accordance with Hess's law. In addition, the specific heat capacity of the compound at T=298.15K was determined to be 1.42+/-0.11J.K -1 .g -1 by RD496-2000 calorimeter. |
