Abstract
Abstract Unlike polyhalides of heavier halogens, polychlorides still remain exotic curiosities. Herein, we report preparation and investigation of complexes Cat 2 {[TeCl 6 ](Cl 2 )} (cat=1‐methylpyridinium ( 1 ) and tetramethylammonium ( 2 )) where dichlorine units are “trapped” by chlorotellurate(IV) anions via a system of non‐covalent Cl⋅⋅⋅Cl interactions. Complex 2 reveals a record thermal stability (>100 °C) for inclusion compounds with Cl 2 , indications that such compounds can be used as solid Cl 2 source.
