Syntheses, crystal structures and thermal analyses of two new ionic complexes based on 3,4-diamino-1,2,4-triazole

Abstract

Two new ionic complexes, (DATr)₂[Li₂(TNR)₂·2H₂O]·2H₂O (1) and (DATr)[Zn(DATr)Cl₃] (2), were synthesized by using 3,4-diamino-1,2,4-triazole (DATr) as outer cation. X-ray single-crystal diffraction analysis revealed that the two complexes crystallize in triclinic and orthorhombic crystal systems, respectively. Differential scanning calorimetry was applied to assess the thermal decomposition behavior and kinetic parameters of decomposition were studied by using Kissinger’s and Ozawa–Doyle’s methods. Furthermore, the critical temperature of thermal explosion and parameters of thermodynamics were obtained.
