Energetic cuprous azide complex: synthesis, crystal structure, and characterization

Abstract

An energetic cuprous azide complex, [Cu₂(2apyz)(N₃)₂] _n (1) (2apyz = 2-aminopyrazine), has been synthesized through hydrothermal method by utilizing the reducibility of H₃PO₃ and structurally characterized by single-crystal X-ray diffraction. Complex 1 has a 2-D layer structure constructed from copper(I) bridged by azide and pyrazine. Catalysis research shows 1 can promote the burning rate of the main component of rocket propellant.
