Abstract

The reaction of the Zintl compound K₄Ge₉ with Te and Ga₂Te₃ in ethylenediamine (en) at 190 °C gave the germanium polytelluride {[Ga(en)₃]₂[(GeTe) ₂(Te₅)^6-(Te⁸)^4-]}n (1). The single-crystal structure analysis revealed that 1 has two different polytelluride fragments: cross-shaped 36-e^- TeTe₄ ^6- anions and boat-shaped 52-e^- Te₈ ^4- rings. The new material is a p-type semiconductor at room temperature and switches to n-type at 380 K.
