N2 - A new coordination compound, [Mn(CHZ)3][C(NO2) 3]2, was synthesized and characterized by elemental analysis, IR and UV spectra, and its crystal structure was determined by X-ray single crystal diffraction. The crystal belongs to the triclinic system and space group P1̄ with a = 0.88737(18) nm, b = 1.1804(2) nm, c = 1.1936(2) nm, β = 83.73(3)°, V= 1,1121(4) nm3, Z = 2, Dc = 1.867 g cm-3. Every Mn(II) ion is six-coordinated to three CHZ molecules through three carbonyl oxygen atoms and three terminal nitrogen atoms to form a distorted octahedral structure. Mn(II) ions, carbohydrazide ligand molecules, and trinitromethanide anions are jointed to a complicated three-dimensional netted structure through coordination bonds, electrostatic forces, and extensive hydrogen bonds. The thermal decomposition character and mechanism was studied by DSC, TG-DTG, and FTIR techniques. The non-isothermal kinetics has also been studied on the exothermic decomposition by using Kissinger's method and Ozawa-Doyle's method. In addition, the impact, friction, and flame sensitivity data were determined. All properties data observed show that the title complex has high energy, good thermal stability, and moderately friction sensitivity.
