A novel cuprous azide complex with the formula of [Cu₂(dmpz)(N₃)₂]_n (1, dmpz: 2,6-dimethylpyrazine) has been synthesized through hydrothermal synthesis with the reducibility of H₃PO₃ and structurally characterized by single-crystal X-ray diffraction method. Single-crystal X-ray diffraction analysis reveals the title complex represents a three-dimensional network structure featuring 2D [CuN₃]_n plane units bridged by bridging dmpz ligands to form a 3D network. Research results reveal that 1 has lower impact sensitivity and friction sensitivity, which may be expected to become insensitive energetic material and have potential applications. Crystal data: monoclinic, space group C2/c, a=17.8599(15), b=8.2889(5), c=14.8076(14) Å, β=113.2580(10)°, V=2014.0(3) Å³, Z=8, S=1.025, the final R=0.0303, wR=0.0825 for 1460 observed reflections with I>2σ(I) and R=0.0386, wR=0.0870 for all reflections. In addition, elemental analysis, IR, and sensitivity characterization are presented.
