Abstract

The Gly–GaF3·3H2O–H2O(HF) system was studied by vibrational spectroscopy methods. A number of complex gallium(III) fluorides were obtained: (GlyH)3[GaF6], (GlyH)(Gly···GlyH)[GaF5(H2O)]·H2O, (GlyH)6[GaF5–F–GaF5]·F and (GlyH)[GaF4(H2O)2·0,5H2O.The vibrational (IR, Raman) spectra of the obtained compounds were analyzed, and band assignments were made. A distorted octahedral structure of the anions was established in the structures of all the obtained compounds, with the outer-sphere glycine cations being in the protonated state, with the outer-sphere glycine cations being in the protonated state.
