Characterization of new oxovanadium(IV) complexes of saccharides

Carbohydr Res. 2000 Oct 20;329(1):41-7. doi: 10.1016/s0008-6215(00)00171-3.

Abstract

Oxovanadium(IV) complexes of the monosaccharides D- and L-arabinose, D-galactose, D-mannose, D-lyxose, D-xylose and the disaccharide maltose were obtained in aqueous solutions at pH 13. Their sodium salts were precipitated with absolute ethanol and characterized by UV-vis spectroscopy (absorption and reflectance), thermo-analytical (TG and DTA) data, magnetic susceptibility measurements and IR-spectroscopy. All the complexes were found to be mononuclear, possessing the VO2+ moiety. The IR spectra were analyzed and discussed in detail allowing one to determine the characteristics of the metal-to-ligand interactions.
