Methods of synthesis of complex connections of rhenium with aminoacetic acid has been developed [K(LH)][RеCl6] and [LH]2[ReCl6] (L=NH2-CH2-COOH;X=Cl-,Br-) in the medium of halogen hydrogen acid.Using methods of ESA and IR spectroscopy, it was established that aminoacetic acid in the said medium has been to protonized to form a part of external cation.
