N2 - An energetic complex [Mg(CHZ) 3](ClO 4) 2 was synthesized by the reaction of carbohydrazide (CHZ) with magnesium perchlorate. The product was characterized by X-ray single-crystal diffraction, elemental analysis, and IR spectroscopy. The crystal belongs to the monoclinic system with space group P2(1)/n. Cell parameters: a=10.034(2)Å, b=8.5069(16)Å, c=21.285(4)Å, β=100.901(3)°, V=1784.1(6)Å 3, Z=4. The central magnesium is six-coordinate with three oxygen atoms of carbonyl groups and three terminal nitrogen atoms of the hydrazine groups from three CHZs to form a distorted octahedron. Differential scanning calorimetry and thermogravimetric-differential thermogravimetric analysis were applied to assess the thermal decomposition behavior. The kinetic parameters were obtained by non-isothermal reaction kinetics. The equation can be expressed as dα/dT = 4 × 10 6.13α 3/4e 8.51×10 3/T. Moreover, the values of critical temperature of thermal explosion, ΔS ≠, ΔH ≠, ΔG ≠, and the energy of combustion were obtained as 284°C, -169.76Jmol -1K -1, 65.46kJmol -1, 154.27kJmol -1, and 6759kJkg -1, respectively.
