Abstract

In our effort to seek for the "green" energetic coordination polymers (CPs), a versatile and multifunctional 1-amino-tetrazol-5-one ligand was synthesized and its complexes with a series of alkaline and earth alkaline metals were prepared and comprehensively characterized. A broad range of differently shaped 1D, 2D, and 3D supramolecular structures for the prepared energetic compounds were found, where each metal was bound in a specific and characteristic fashion. All prepared CPs show very good thermostability, with decomposition temperatures above 236 °C and remarkable insensitivity to mechanical impact and friction (impact sensitivity > 40 J, friction sensitivity > 360 N). In terms of detonation performance, our CPs were calculated to have detonation velocities in the range of 6.8-8.1 km·s -1 and detonation pressures in the range of 16.5-24.5 GPa. Upon their combustion, new materials show a range of characteristic flame colors (from yellow to blue), making these compounds as promising components for various "green" pyrotechnic formulations.
