Source of material
An amount of 25.9 mL of acetic anhydride was added to a 100 mL four-necked flask, cooled in an ice water bath, and 13.8 g of 3-nitropyrazole was slowly added to the reaction flask in batches, stirred for 10 min, then 7.8 mL of fuming nitric acid was slowly added dropwise. After the addition is completed, the system is heated to 50 °C, and the reaction is carried out at a constant temperature for 4 h. After the reaction is completed, the reaction solution is poured into 200 g of ice water to precipitate a large amount of white solid, and the filtrate is evaporated at room temperature to obtain colourless crystals.
Experimental details
All H atoms were identified in difference Fourier syntheses. With C—H bond lengths constrained to 0.95° and Uiso(H) = 1.2Ueq(C) for the hydrogen atoms of pyrazole ring, C—H bond 0.98° and Uiso(H) = 1.5Ueq(C) for methyl group, N—H bond 0.874° and Uiso(H) = 1.2Ueq(N).
Comment
Nitropyrazole compounds have high nitrogen content, high enthalpy of formation, high density, low sensitivity and environment-friendly characteristics, and have become a research hotspot in the field of energy-containing materials in recent years [4], [5], [6]. 3,4,5-Trinitro-1H-pyrazole (TNP) is widely studied because it is the only pyrazole compound with full carbon nitrification. TNP and its derivatives can be widely used in pesticide, medicine, dye, energy-containing materials and other fields, which has far-reaching research significance and broad development prospects [7], [8]. In order to study the synthesis mechanism of TNP, the title compound was prepared by nitrification reaction of 3-nitropyrazole, which was slowly added into acetic anhydride cooled by ice bath giving a cocrystal.
In the crystal structure of the title compound, 4-nitropyrazole molecules exist in pairs with acetic acid molecules, forming a cocrystal structure. 4-Nitropyrazole molecule is often used as a ligand to form coordination compounds with certain molecules [9], [10], and the cocrystal structure of the title compound is also relevant. The bond angle between the atoms in the 4-nitropyrazole molecule some what different from the bond angle between the atoms in the 4-nitropyrazole single crystal, which may be due to the presence of the acetic acid molecule and the corresponding hydrogen bond [11]. By NH⋯O and OH⋯N hydrogen bonds two acid molecules and two pyrazole molecules are linked to a ring.
