Abstract

The compound BaBiTe₃ was prepared by the reaction of Ba/Bi/Te at over 700 °C either in K₂Te₄ or BaTe₃ flux and was recrystallized in a Ba/BaTe₃ flux. The black rod-shaped polycrystalline material crystallizes in the orthorhombic space group P2₁2₁2₁ with a = 4.6077(2) angstroms, b = 17.0437(8) angstroms, c = 18.2997(8) angstroms. Its structure is made of interdigitating columnar anionic [Bi₄Te₁₀(Te₂)]_∞ `herring-bone' shaped segments which arrange into layers with Ba²⁺ ions between them. The electrical conductivity, thermopower, thermal lattice conductivity, infrared absorption properties of this material suggest it is a narrow gap semiconductor.
