title: [Synthesis and characterization of complex of Na2[Cu5(Shi)4].4H2O].
abstract: The complex, which is formed by reacting copper (II) with salicylhydroxamic acid (H3Shi), has been synthesized. The chemical formula of the complex was determined to be Na2[Cu5(Shi)4].4H2O by elemental analysis and spectrometric titration. The structure and the properties were tentatively investigated by using UV-Vis, IR, NMR, TG, fluorescence, molecular modeling and magnetic susceptibility measurement. The results show that the UV absorption peak corresponding to the pi-->pi* transition shifts towards red 25 nm, the d proton of salicylhydroxamic acid behaves as that of alkyl hydrocarbon in NMR and there is a strong magnetic interaction among the copper (II) ions in the complex.
