✦ Synopsis

A novel energetic coordination compound [Co(DAT) 6 ](ClO 4 ) 2 has been synthesized by using 1,5-diaminotetrazole (DAT) as a ligand and its structure has been characterized using X-ray single crystal diffraction, elemental analysis and FT-IR spectroscopy. The central cobalt(II) cation is coordinated by six N atoms from six DAT molecules to form a six-coordinated and distorted octahedral structure. Di-dimension layer structure was formed by the extensive intermolecular hydrogen bonds between DAT ligands and 4 ClO -anions along a-axis and b-axis. Thermal decomposition mechanism of [Co(DAT) 6 ](ClO 4 ) 2 was investigated based on differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transform infrared (FT-IR) spectra. The kinetic parameters of the first exothermic process were studied by applying the Kissinger's and Ozawa-Doyle's methods. Additionally, the sensitivities of this complex were tested. The results of all the studies show that [Co(DAT) 6 ](ClO 4 ) 2 has an extreme potential application as an energetic material.
