The sesquitelluride Sc₂Te₃

A. Assoud and H. Kleinke

Abstract: Scandium sesquitelluride, Sc₂Te₃, was obtained as a side product by reacting the elements Sc, Ni and Te at 1073 K in an evacuated silica tube. This is the third modification of Sc₂Te₃, which crystallizes in the orthorhombic space group Fddd and adopts the Sc₂S₃ structure type [Dismukes & White (1964). Inorg. Chem. 3, 1220-1228]. The structure consists of edge-sharing (slightly distorted) ScTe₆ octahedra and may be regarded as a defect variant of the NaCl type.
