Аннотация: New compounds of sparfloxacin (C19H22F2N4O3, SfH) and levofloxacin (C18H20FN3O4, LevoH) with mineral acids, namely, sparfloxacinium bromide (SfH · HBr, I) and levofloxacindium diperchlorate (LevoH · 2HClO4, II), have been synthesized and characterized by X-ray diffraction. Crystallographic data are a = 7.7151(7) Å, , b = 26.109(3) Å,с = 10.008(1) Å, β = 103.556(1)°, V = 1959.7(3) Å3, space group P21/n, Z = 4 for I and a = 9.727(6) Å, b = 20.440(12) Å, с = 12.286(7) Å, β = 104.327(8)°, V = 2367(2)Å3, space group P21, Z = 4 for II. The structures of these compounds are stabilized by intra- and intermolecular hydrogen bonds and π–π interaction between SfH2 + or LevoH3 2+ ions. © 2016, Pleiades Publishing, Ltd.
