Synthesis and characterization of a three-dimensional coordination polymer based on copper(II) nitrate and a tridentate tetrazole ligand

Abstract

Tris(2-(1H-tetrazol-1-yl)ethyl)amine (1) was synthesized as gas-generating agent and characterized by vibrational (IR) and NMR spectroscopy. The energetic properties were determined by bomb calorimetric measurements along with calculations using the EXPLO5 software. Tris(2-(1H-tetrazol-1-yl)ethyl)amine (1) was used for further reactions with copper(II) nitrate to form a three-dimensional coordination polymer 3. Both compounds were characterized by single crystal X-ray diffraction. The thermal stability was determined by DSC measurements and the physical stability by BAM standards. Tris(2-(1H-tetrazol-1- yl)ethyl)amine (1) proved to be suitable as gas-generating agent with sufficient physical and thermal stabilities. The low thermal stability of the copper complex 3 disqualifies it as potential colorant agent for pyrotechnical applications. © 2009 Verlag der Zeitschrift für Naturforschung, Tübingen.
