Solid state complexes of zinc (II) with cefazolin and cefotaxime
When reacting aqueous solutions of zinc chloride and sodium salts of cefazolin (NaCzl) and cefotaxime (NaCxm) prepared and isolated in solid state zinc complexes of cefazolin and cefotaxime composition Zn(Czl)2•H2O and Zn(Cxm)2•H2O. Complexes sparingly soluble in water and in ethanol. The compounds were studied by IR spectroscopy, electron microprobe analysis and thermal TG / DSC analysis. The resulting complexes are chelating structure.
