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.
