Abstract
AbstractThe ternary compound LiInTe2, synthesized by direct reaction of the elemental components, crystallizes in the tetragonal chalcopyrite structure (space group I42d) with lattice parameters a = 0.6419(2) and c = 1.2486(3) nm. LiInTe2 remains in the chalcopyrite structure up to the melting temperature of (935 ± 5) K. Infrared reflectance spectra measured in the wavenumber range from 40 to 4000 cm−1 yield two infrared active optical modes. An analysis of the mode frequencies in terms of the Keating model shows that the LiTe bond is considerably weaker than the InTe bond.
