N2 - Two novel energetic coordination compounds Zn 2(DAT) 5(H 2O) 3(TNR) 2 and Co 2(DAT) 5(H 2O) 3(TNR) 2 were synthesized and their structures were characterized by elemental analysis and FT-IR spectroscopy. The crystal structures were determined by single-crystal X-ray diffraction. The results reveal that the compounds have similar molecular structures and the crystals belong to the triclinic system, space group P1̄ with a = 11.491(3), b = 13.564(3), c = 15.496(3) Å, V = 2180.4(8) Å 3, C 17H 28 Zn 2N 36O 19, M r = 1203.02 g·mol -1, D c = 1.832 g·cm -3, μ(MoKα) = 1.221 mm -1, F(000) = 1223, Z = 2, R = 0.0596 and wR = 0.1514 for 11289 observed reflections (I > 2σ(I)) for Zn 2(DAT) 5(H 2O) 3(TNR) 2 and a = 11.5291(13), b = 13.4894(15), c = 15.4852(17) Å, V = 2164.8(4) Å 3, C 17H 28Co 2N 36O 19, M r = 1190.14 g·mol -1, D c = 1.826 g·cm -3, μ(MoKα) = 0.888 mm -1, F(000) = 1211, Z = 2, R = 0.0576 and wR = 0.1431 for 11218 observed reflections (I > 2σ(I)) for Co 2(DAT) 5(H 2O) 3(TNR) 2, respectively. The thermal decomposition characteristics of the compounds were investigated using differential scanning calorimetry and thermal gravimetry-differrential thermal gravimetry. The results of thermal decomposition processes were similar for the two compounds. Both undergo four-step decomposition after the loss of coordinated H 2O molecules. The final solid residues for the two D AT complexes were the corresponding metal oxides. The kinetic parameter of the first exothermic process of the compounds was studied by applying the Kissinger and Ozawa-Doyle methods. The thermodynamic parameters of the activation could be calculated. Sensitivity tests revealed that Co 2(DAT) 5(H 2O) 3(TNR) 2 was more sensitive than Zn 2(DAT) 5(H 2O) 3(TNR) 2.
