Abstract

The cesium polytelluridostannate(IV) Cs₂SnTe₄ has been prepared by methanolothermal reaction of Cs₂CO₃ with Sn and Te at 190 °C. The crystal structure contains chain anions ¹ _∞[SnTe^2- ₄] in which individual SnTe₄ tetrahedra are linked via Te -Te bonds of length 2.814(3) Å. Weak Te∙∙∙Te secondary bonds of length 3.631(3)-3.663(3) Å connect neighbouring chains into a framework structure. Nine Te atoms from three chain anions participate in the coordination sphere of the cesium cation.
