Abstract

Two zinc coordination polymers, {[Zn(HATr)₂](NO₃)₂}_n (1) and {[Zn₂(HATr)₄](ZnCl₄)(NO₃)₂·H₂O}_n (2), were synthesized from reactions of 3-hydrazino-4-amino-1,2,4-triazole dihydrochloride (HATr·2HCl) with Zn(NO₃)₂. The polymers were characterized by single-crystal X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), elemental analysis, and differential scanning calorimetry. The crystal structures revealed that 1 and 2 have 1-D-chain structures, which were further assembled to form 3-D-frameworks by hydrogen bonds. Thermal analyses showed that these two compounds have thermal stability up to 280 °C. The energies of combustion, enthalpies of formation, critical temperatures of thermal explosion, entropies of activation (ΔS^≠), enthalpies of activation (ΔH^≠), and free energies of activation (ΔG^≠) were also measured and calculated. Furthermore, the sensitivities of 1 and 2 toward impact, friction, and static were determined, which revealed that 1 and 2 were less sensitive than Ni(N₂H₄)₃(NO₃)₂.
