1D and 2D Polybromotellurates(IV): Structural Studies and Thermal Stability

Abstract

Three novel polybromotellurates(IV) were obtained by reactions of TeO 2 in conc. HBr with Br 2 and tri‐ or tetraalkylammonium salts. They contain [TeBr 6 ] 2– octahedra connected by {Br 2 } linkers into one‐ or pseudo‐two‐dimensional networks. The thermal stability of the products was investigated by TGA; additionally, all compounds were characterized by Raman spectroscopy. Energies of Br ··· Br interactions were estimated by DFT calculations (QTAIM method).
