ChemInform Abstract: Synthesis and Characterization of Sodium Polytellurides in Liquid Ammonia Solution.

ChemInform Abstract

The Na-Te system has been investigated in liquid NH₃ by UV-VIS spectroscopy and elemental analysis of the isolated products. Na₂Te₂ and Na₂Te₃ are found to be stable in liquid NH₃. An intermediate species, which may be NaTe, is formed during the sequential reaction of elemental Na and Te, and is suggested to be a precursor of Na₂Te. Na₂Te is either insoluble in NH₃ or does not absorb in the UV-VISregion. No polytelluride higher than Na₂Te₃ is formed under the conditions used.
