Description	Experimentální a teoretické studie prvních vanadocenových komplexů alfa-aminokyselin připravených z vanadocendichloridu (cs) The first bioinorganic vanadocene(IV) complexes of alpha-amino acids ([Cp2V(aa)]Cl, Cp = eta(5)-C5H5, aa = glycine, L-alanine, L- valine) were prepared by reaction of vanadocene dichloride ([Cp2VCl2]) and alpha-amino acids in aqueous methanol. Analogous cationic complexes with PF6- counterions were obtained by metathetical reactions of the chloride precursors with KPF6. These compounds are of great interest as model systems for the vanadocene moiety binding to proteins. All complexes have been characterized by elemental analyses and IR, Raman and EPR spectroscopies. On the basis of EPR spectra, a chelate in all the studied complexes was proposed, formed by the carboxylato and amino groups. This structure has also been confirmed by density functional theory (DFT) calculations.
