Аннотация: The structure of two new ionic compounds of sparfloxacin (C19H22F2N4O3, SfH), SfH(3)[ZnCl4]aEuro cent 1.5H(2)O (I) and SfH(3)[CdBr4]aEuro cent H2O (II), is determined. Crystallographic data are as follows: for I a = 14.505(3) , b = 12.615(3) , c = 29.118(7) , V = 5254(4)(3), space group Pbca, Z = 8; for II a = 13.2822(5) , b = 10.2564(4) , c = 21.3250(8) , beta = 100.7248(4)A degrees, V = 2854.3(3) (3), space group P2(1)/ (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 pi-pi interaction between the SfH (3) (2+) ions.
