Synthesis, characterisation and energetic performance of a new copper complex based on 3,4,5-trinitro-1H-pyrazole

Abstract. The design of both initiators and pyrotechnics that are more environmentally benign ("green") relies on the use of nitrogen- or oxygen-rich materials that act as efficient oxidizing agents to reduce formation of particulates, together with less toxic metals such as copper. Herein, we report the synthesis and characterization of a new copper complex based on the trinitropyrazolate (TNP^-) ligand - ammonium copper (tetrakis)trinitropyrazolate [(NH4+)2CuII(TNP-)4], which displays remarkable thermal stability, combined with a high energy output. It is therefore a promising candidate to
