Аннотация: The structures of three ionic compounds of levofloxacin (LevoH or Ci18H20FN3O4) − LevoH3[CoCl4]-H2O (I), LevoH3[ZnBr4]·H2O (II), LevoH3[CuBr4]-H2O·(III) are determined. The crystals of I-III are monoclinic; in compound III, the particles are packed so that the direction of the screw axis does not coincide with the largest unit cellПоказать полностьюparameter. The asymmetric unit of the unit cell contains two LevoH3 2+ and CoCl4 2− ions and two crystallization water molecules in I; two LevoH3 2+ and MBr4 2− (M = Cu, Zn) ions and two crystallization water molecules in II and III. The absolute structure of the crystals and the configuration of the chiral center of the levofloxacinium cation S are determined. The structures are stabilized by multiple hydrogen bonds, X−Y π and π-π interactions. © 2019, Pleiades Publishing, Ltd.
