The reported novel compounds [H3O·(dibenzo-18-crown-6)][Te2Br9], [H5O2][Te2Cl9]·2C4H8O2 and [H5O2·(bis-dibromo-dibenzo-24-crown-8)]2[Se3Br8] highlight the large structural and chemical variety of halogen chalcogen chemistry. Both [Te2X9]− anions (X = Cl, Br) consist of one square pyramidal TeX5 fragment connected to a TeX6 octahedron by a common edge. The linear [Se3Br8]2− anion is built by three square planar SeBr4-fragments. The three counterions offer a convenient possibility for controlled synthesis of supramolecular oxonium systems.
