Abstract
The composition Ba1.95In2O4.9F0.1 from homogeneity range Ba2 â 0.5xIn2O5 â xFx with x = 0.1 was obtained by a solid state method, the crystalline structure and local structure have been investigated (X-ray, infrared and Raman spectroscopy, NMR). The introduction of fluorine in oxygen sublattice is accompanied by decreasing some In-O distances. The phase is capable of dissociative dissolution of water, and as a result the nonequivalent OHâ-groups are formed. The fluorine doping leads to the increase of hydrogen bonds of OHâ-groups and this reflects increase in some O-Ð distances. For Fâ-doped sample the protons are weaker coupled to the lattice and become more mobile compared to Ba2In2O4(OH)2.
