摘要

Through a one-pot reaction of NiCO(3)2Ni(OH)(2)H2O, aminourea hydrochloride (SCZHCl) and 2,4,6-trinitroresorcinol (TNR), a halogen-free and lead-free chelating energetic material (CEM) [Ni(SCZ)(3)]TNR was synthesized. We confirmed the structure of [Ni(SCZ)(3)]TNR by infrared spectroscopy, X-ray diffraction, and elemental analysis. The complex is triclinic with P (I) over bar (2) space group. Cell parameters are: a = 1.04008(17) nm, b = 1.3719(2) nm, c = 1.4897(2) nm, V = 2.0337(6) nm(3), Z = 4. The central nickel atom is six-coordinate with three oxygen atoms of carbonyl groups and three terminal nitrogen atoms of the hydrazine groups from three SCZs to form a distorted octahedron. Differential scanning calorimetry and analysis applied to assess the thermal decomposition behavior. The DSC curve with a linear heating rate of 10 degrees Cmin(-1) shows that [Ni(SCZ)(3)]TNR is thermally stable with one exothermic peak temperatures of 78.8 degrees C and two exothermic peak temperatures of 216.8 degrees C and 308.1 degrees C. The kinetic parameters were obtained by non-isothermal reaction kinetics. The equation can be expressed as lnk = 24.49-243.3x10(3)/RT. Moreover, the values of the critical temperature of thermal explosion, Delta S-not equal, Delta H-not equal, Delta G(not equal), and the enthalpies of formation were obtained as 206.5 degrees C, -145.543 Jmol(-1)K(-1), 237.18 kJmol(-1), 305.84 kJmol(-1), and -2.65 MJkg(-1), respectively.
