Abstract

High pressure, high temperature technics were employed to successfully synthesize HoTe1.7, ErTe1.7, TmTe1.7, LuTe1.7, YTe1.7, and LuTe3. The pressure-temperature regions in which synthesis of each compound is successful were determined. Pressures to 100 kbars concurrently with temperatures to 1200 °C were used in an attempt to prepare ScTe1.7 and ScTe3, but these efforts met with failure. X-ray studies of these new compounds confirmed that they are extensions of the LTe2-X (0≤x<0.3) and LTe3 series (L = lanthanide) previously reported through dysprosium for LTe2-X and through thulium for LTe3. The lattice parameters are reported and compared (versus lanthanide ionic radius) with those of the previously known analogs.
