Synthesis, Crystal Structure and Characterization of Energetic Monovalent Copper Azide Complex: [Cu2(dmpz)(N3)2]n

A novel cuprous azide complex with the formula of [Cu-2(dmpz)(N-3)(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) angstrom, beta = 113.2580(10)degrees, V =2014.0(3) angstrom(3), Z= 8, S= 1.025, the final R= 0.0303, wR= 0.0825 for 1460 observed reflections with I> 2 sigma(I) and R= 0.0386, wR = 0.0870 for all reflections. In addition, elemental analysis, IR, and sensitivity characterization are presented.
