| Popis: | Indium(III) fluoride complexes with β-alanine amino acid (β-AlaH)[InF4(H2O)2]·0.5H2O and (β-AlaH)2[InF5(H2O)]·2H2O have been synthesized for the first time and investigated by the methods of single crystal X-ray diffraction, 19F, 1H NMR spectroscopy, thermogravimetry (TG, DTG, DTA), and DSC. The crystal structure of (β-AlaH)[InF4(H2O)2]·0.5H2O has been investigated at 296 K, whereas that of (β-AlaH)2[InF5(H2O)]·2H2O – at 173 K. The structure of (β-AlaH)2[InF5(H2O)]·2H2O was found to be disordered. Two disordered "resonance" structures of the β-alaninium cation with different arrangement of the proton in the carboxylic groups were obtained. The thermal behavior and character of ionic motions in the investigated compounds have been studied. |
