Energetic Cuprous Azide Complex: Synthesis, Crystal Structure and Effection on the Thermal Decomposition of HMX

A novel energetic cuprous azide complex with the formula of [Cu2(dmpyz)(N3)2] n (1) (dmpyz: 2,5-dimethylpyrazine) has been synthesized through hydrothermal method by utilizing the reducibility of H3PO3 and structurally characterized by X-ray single crystal diffraction method. Single crystal X-ray diffraction analysis reveals complex (1) featuring a two-dimensional layer structure constructed from copper(I) atoms bridged by azide anion and further connected by pyrazine ligand to form a 3D network. The result of catalysis research reveals it can promote the burning rate of main component of rocket propellants.
