Syntheses and Infrared Spectra of Solid Complexes of Monovalino-Hexaquo-Rare Earth Chlorides
Abstract:
The title complexes Ln(Val)Cl3·6H2O (Ln=La,Nd,Sm,Gd,Er) have been synthesized in aqueous solution. The compositions of the complexes were determined by ele-mental analysis and EDTA titration. The infrared spectra of the complexes were measured with principal spectral bands being assigned. The results showed that the valine molecules are zwitterions in the complexes and coordinate to rare earth ions through carboxyl groups, and the six water molecules coordinate to rare earth ion too. The La ang Nd complexes may be one dimensional chain complexes of infinite length and the others dinuclear complexes.
