N2 - Nitro compounds have been actively researched as driven by their potential to be high-performing energetic materials. Herein, three new nitro compounds including semicarbazide 3,5-dinitrobenzoate, (SCZ)(DNBA), manganese 3,5-dinitrobenzoate dihydrate, [Mn(DNBA)2(H2O)2]n, and bis(semicarbazide) manganese(II) 3,5-dinitrobenzoate, Mn(SCZ)2(DNBA)2, were synthesized and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction analysis. The results indicated that the above mentioned compounds are ionic, polymeric, and molecular in nature, respectively. Moreover, their thermal decomposition properties were assessed by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Their non-isothermal reaction kinetics parameters, critical temperature of thermal explosion (Tbp), entropy of activation (ΔS≠), enthalpy of activation (ΔH≠), and free energy of activation (ΔG≠) of the exothermic decomposition process were also calculated. Results suggest that there was a relationship between the structure and thermal stability.
