Synthesis and Properties of [Cd(HTRTR)(2)(H2O)(4)](HTNR)(2) as an Energetic Complex

The energetic complex, [Cd(HTRTR)(2)(H2O)(4)](HTNR)(2) {HTRTR = 4-[3-(1,2,4-triazol-yl)-1,2,4-triaozle; HTNR- = styphnic acid anion) was synthesized and characterized by FT-IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction. It crystallizes triclinic in space group P [a = 8.156(2) angstrom, b = 8.374(2) angstrom, c = 13.267(4) angstrom, = 84.925(11)degrees, = 87.016(11)degrees, = 63.683(5)degrees, V = 808.9(4) angstrom(3), = 1.940 gcm(-3)]. The Cd-II ion is six-coordinate with two HTRTRs and four water molecules. The thermal stabilities were investigated by differential scanning calorimetry (DSC). Non-isothermal reaction kinetic parameters were calculated by Kissinger's and Ozawa-Doyle's methods to obtain E-K = 144.0 kJmol(-1), lgA(K) = 14.22, and E-O = 144.3 kJmol(-1). The values of thermodynamic parameters, the peak temperature while 0 (T-p0), free energy of activation (G), entropy of activation (S), and enthalpy of activation (H) were obtained. Additionally, the enthalpy of formation was calculated by Hess's law on the basis of the experimental constant-volume heat of combustion measured by bomb calorimetry, obtaining H-f degrees(298) = 4985.5 kJmol(-1). Finally, the sensitivities toward impact and friction were assessed according to relevant methods. The result indicates it as an insensitive energetic material.SCI(E)ARTICLEztlbit@bit.edu.cn13761-76564
