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.
