Abstract: 

The reaction of ReCl4 with Te and TeCl4 in a sealed evacuated glass ampoule at 230°C yields silvery, lustrous, moisture sensitive crystals of Te8[ReCl6]. The crystal structure determination (monoclinic, C2/c, Z = 8, a = 1232.5(9) pm, b = 976.4(4) pm, c = 3114(2) pm, β = 90.85(5)°) shows, that the compound consists of octahedral [ReCl6]2 and of Te82+ ions. The cations are eight‐membered rings in an exo‐endo conformation and are isostructural to the already known S82+ and Se82+. The mean Te-Te bond length in the ring is 272 pm, the shortest transannular Te-Te bond is 315 pm. Te8[ReCl6] contains a new form of the Te82+ polycation. In contrast, the cations in the previously reported Te8[WCl6]2 have a pronounced bicyclic structure and intercationic bonds leading to an ondulated polymeric Tenn/4+ chain while the cations in the structure of Te8[ReCl6] are isolated from each other and surrounded by anions only.
