1 Source of material
N,N-dimethylformamide was used as the base liquid, and potassium salt of 2,4,5-trinitroimidazole and 18-crown-6 were added to the reactor in a molar ratio of 1:1. The reaction was carried out at 323.15 K for 1 h, and the light yellow solid product was recrystallized in acetone solution to obtain the title product. X-ray single crystal diffraction was performed on the crystal.
2 Experimental details
Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.
3 Comment
Trinitroimidazole compounds are energetic compounds with high potential. 5 2,4,5-Trinitroimidazole is a compound in which the H of the 2,4 and 5 positions of the imidazole ring is substituted by nitro, and its sensitivity is lower than that of hexogen and octogen. Normally, Na+ or K+ is substituted to N of 2,4,5-trinitroimidazole to make it a salt to increase its energy and stability.
The asymmetric unit of the title compound is half a molecule. All bond lengths and angles are within the expected range. As shown in the figure, the title compound is a 1:1 complex of 18-crown-6 with K+ and trinitroimidazole. K+ and 18-crown-6 are connected by metal ion coordination bonds. 18-Crown-6 and nitroimidazole form bonds with oxygen atoms in the upper nitro group of imidazole positions 4 and 5 through K+. The dihedral angle between the plane of C15, C14, N2, N3 and O11 atoms in nitroimidazole and the plane of K1, O1 and O3 in crown ether is 24.27°.
General symmetric crown ethers have high ability to bond cations. 6 , 7 , 8 , 9 When the metal ion is matched to the crown ether size, it gives a strong ion-dipole interaction and shows a strong ionic bond and ability. In the 18-crown-6 coordination of K+, the size matching gives a strong ionic dipole interaction. 10
