Аннотация: The structure of two new ionic compounds of sparfloxacin (C19H22F2N4O3, SfH), SfH3[ZnCl4]•1.5H2O (I) and SfH3[CdBr4]•H2O (II), is determined. Crystallographic data are as follows: for I a = 14.505(3) Å, b = 12.615(3) Å, c = 29.118(7) Å, V = 5254(4)Å3, space group Pbca, Z = 8; for II a = 13.2822(5) Å, b = 10.2564(4) Å, c = 21.3250(8) Å, β = 100.7248(4)°, V = 2854.3(3) Å3, space group P21/ n, Z = 4. The structures of the compounds are stabilized by intra- and intermolecular hydrogen bonds and the structure of I is additionally stabilized by the π-π interaction between the SfH 3 2+ ions. © 2015 Pleiades Publishing, Ltd.

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.
