Synthesis, crystal structure and properties of energetic complexes constructed from transition metal cations (Fe and Co) and ANPyO

Abstract

Two transition metal energetic complexes with ligand 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) have been synthesized and structurally characterized by FT-IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. The thermal decomposition processes and the kinetic parameters of the two complexes were studied by means of the TG-DTG and DSC technologies. The compatibility of the two complexes with RDX (1,3,5-trinitrohexahydro-1,3,5-triazine), HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine), NC and Al powder was also investigated. DSC measurements show that both complexes have significant catalytic effects on the thermal decomposition of ammonium perchlorate. Sensitivity tests reveal that the two complexes are more insensitive to mechanical stimuli than ANPyO.
