Synthesis, Crystal Structure, and Properties of Energetic Copper(II) Complex based on 3,5-Dinitrobenzoic Acid and 1,5-Diaminotetrazole

• 摘要：

  Energetic copper(II) complexes based on 3,5-dinitrobenzoic acid (HDNBA) and 1,5-diaminotetrazole (DAT), Cu(DNBA)₂(H₂O)₂ (1) and Cu(DAT)₂(DNBA)₂ (2) were synthesized and characterized by elemental analysis, IR spectroscopy, single-crystal and powder X-ray diffraction. In both complexes, Cu^II was coordinated to a plane tetragon, by four oxygen atoms from two DNBA^– ions and two coordinated H₂O molecules for 1, and by two oxygen atoms and two nitrogen atoms from different DNBA^– ions and DAT ligands for 2. Differential scanning calorimetry (DSC) and thermogravimetry (TG) analyses were employed to measure the thermal decomposition processes and non-isothermal kinetics parameters of the complexes. The thermal decomposition onset temperatures of 1 and 2 are 321 and 177 °C. The apparent activation energies of the first exothermic decomposition peaks of 1 and 2 are 247.2 and 185.2 kJ·mol^–1. Both 1 (35 J, > 360 N) and 2 (12.5 J, > 360 N) are less sensitive than RDX. The catalytic effects on the decomposition of ammonium perchlorate (AP) of 1 and 2 were studied by DSC. All results supported the potential applications of the energetic complexes as additives of solid rocket propellants.
