Article Synopsis
  • Researchers prepared a co-crystal of the energetic molecule 3-nitro-1,2,4-triazol-5-one (NTO) and 4,4'-bipyridine (BIPY) and studied its structure using advanced techniques up to high pressures of 5.93 GPa.
  • No changes in phase or proton transfer were found at these pressures, although crystal quality worsened at even higher pressures, leading to complex diffraction patterns.
  • Computational models revealed that pressure affects the co-crystal’s color and structural properties, causing proton migration and indicating that the co-crystal has lower impact sensitivity compared to NTO, despite their similarities.

Reduction of copper(ii) chloride using sodium ascorbate in the presence of pure sodium 5-nitro-tetrazolate (NaNT) forms copper(i) 5-nitrotetrazolate - a known initiatory explosive (DBX-1) - and the novel mixed-ligand copper(i) chloride 5-nitrotetrazolate coordination polymer Cu3Cl(N4C-NO2)2, as well as mixtures of both. The reaction is controlled by the presence of seed crystals and transition metal compounds other than CuCl2. Cu3Cl(N4C-NO2)2 is obtained as a wine-red, air stable, water-insoluble, crystalline and highly sensitive explosive material with a greater crystal density, lower thermal stability and a higher sensitivity toward hydrolysis and shock than DBX-1.
