Quantum chemistry methods (DFT B3LYP/6-31G* (3-21G)) were used to calculate the three-dimensional and electronic structure of 4-chloro-3,5-dinitro- and 3,4,5-trinitropyrazoles, as well as their model σ-complexes. Possible reasons for the peculiar reactivity of 3,4,5-trinitropyrazole, 4‑chloro-3,5-dinitropyrazole, and their derivatives were examined.
