Abstract
AbstractSynthesis and X-ray structural determination of three halogenated nitroimidazo[1,2-a]pyridine phenylsulfonyl derivatives are reported. (2) is monoclinic P21/c with a = 9.6679(1), b = 11.3642(2), c = 15.2189(2)Å, β = 105.9053(7)°; (3) is triclinic P −1 with a = 8.5556(2), b = 13.1191(3), c = 15.5132(4)Å, α = 76.0110(8), β = 89.1768(8), γ = 78.953(2)°; (4) is monoclinic P21/c with a = 15.3353(2), b = 8.8621(2), c = 11.4189(3)Å, β = 90.9704(7)°. In the title compounds that differ by the nature and number of halogen substituents, the arylsulfonyl moieties are oriented differently relatively to the nitroimidazopyridine. Moreover non-classical intermolecular interactions are revealed by the X-ray analysis.Graphical AbstractThe X-ray structures of three halogenated nitroimidazo[1,2-a]pyridine phenylsulfonyl derivatives reveal different intermolecular interactions within the crystals.
