- Crystal and molecular structure of imidazole derivatives with different substituents
-
The crystal and molecular structures of 1-Methyl-2-Isopropyl-5-Nitroimidazole (A) and 1-Methyl-2(Thiophenyl)-Methyl-5-Nitroimidazole (B) derivatives were determined by X-ray diffraction methods. The compound A, C7H11N3O2, crystallises in the monoclinic space group P21/c with a = 9.9582(2) angstrom, b = 6.5240(4) angstrom, c = 13.5560(3) angstrom, β = 99.8930(17)°, V = 867.6(5) angstrom3, Z = 4, Dcalc = 1.295 Mg/m3, μ = 0.813 mm-1, F000 = 360, CuKα = 1.5406 angstrom and R = 0.09. The five membered ring with two nitrogen atoms is planar. Layering is observed down a and b axes. The compound B, C11H11N3O2S, crystallises in the triclinic space group P1 with a = 6.270(10) angstrom, b = 27.874(12) angstrom, c = 12.960(3) angstrom, α = 90°, β = 89.90°, γ = 90°, V = 2266(35) angstrom3, Z = 8, Dcalc = 1.461 Mg/m3, μ = 2.504 mm-1, F000 = 1040, CuKα = 1.5406 angstrom and R = 0.11.

- Production of 1-alkyl-5-nitroimidazoles
-
1-Alkyl-5-nitroimidazoles are prepared by reacting a 5-nitroimidazole with an alkylating agent in the presence of an aliphatic carboxylic acid. The products are intermediates for the production of dyes, textiles auxiliaries and insecticides.
