Abstract

Ammonium and guanidinium difluoroiodate(V), [NH4]+[IF2O2] (1a) and [C(NH2)3]+[IF2O2] (1b), and diazidoglyoxime, [N3C=N–OH]2 (2) were synthesized and the molecular structures in the solid state of 1b and 2 were elucidated by single-crystal X-ray diffraction. 1b: Pequation image, a = 6.6890(5), b = 10.2880(6), c = 10.30.92(8) Å, α = 105.447(6), β = 108.568(7), γ = 91.051(5)°, V = 644.08(8) Å3, ρ = 2.650 g·cm–3; 2: P21/n, a = 4.4211(3), b = 13.7797(9), c = 4.9750(3) Å, β = 98.735(6), V = 299.57(3) Å3, ρ = 1.886 g·cm–3. The suitability of compounds 1a and 1b as active ingredients for agent defeat weapons (ADW) with biocidal activity has been shown in detonation tests using geobacillus stearothermophilus spores. In addition, a complete energetic characterization of the promising primary explosive 2 is given.
