New compounds of sparfloxacin (CHFNO, SfH) and levofloxacin (CHFNO, LevoH) with mineral acids, namely, sparfloxacinium bromide (SfH · HBr, I) and levofloxacindium diperchlorate (LevoH · 2HClO, 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) Å, space group P2/ 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)Å, space group P2, Z = 4 for II. The structures of these compounds are stabilized by intra- and intermolecular hydrogen bonds and π-π interaction between SfH or LevoH ions. [ABSTRACT FROM AUTHOR] |
