Abstract
Glasses based on gallium and indium trifluorides are investigated by IR and19F NMR spectroscopy. An analysis of the IR data showed that the octahedral complexes [GaF6]3− and [InF6]3− are the main structural units of these glasses; the nets of indium and gallium glasses differ in the order of binding between the glassforming complexes. An analysis of NMR data also revealed considerable differences in the structure of these glasses as judged by the effect of the type of alkaline cation on the state of the fluoride subsystem. The gallium net is a threedimensional net consisting of octahedral complexes linked by three edges (uniform conjunction); the indium net has a nonuniform conjunction — by two edges and two vertices.
