Abstract
A new compound C18H22FN3O·[CdBr4]2-·2H2O, C18H20FN3O4-levofloxacin (LevoH) is synthesized and its crystal and molecular structure is determined. Crystallographic data for levofloxacindi-um cadmium tetrabromide dihydrate C18H26CdBr4FN3O6 are as follows: a = 8.3815(8) Å, b = 27.318(3) Å, с = 12.066(1) Å, β = 107.105(1)°, V = 2640.5(4) Å3, P21 space group, Z = 4. Hydrogen bonds form a branched three-dimensional network linking LevoH CdBr and water molecules. The structure is also stabilized by the π-π interaction of LevoHaromatic rings.
