of the triflate anion, namely the trichlate [Cl3CSO3]− and the tribrate [Br3CSO3]− are synthesized as their lithium salts. The compounds display molecularstructures with the anions, the lithium cations and water molecules arranged into dimers [Li2(X3CSO3)2(H2O)4] (X=Cl, Br). The figure shows both dimers, partly in an ORTEP style and partly as a Lewis formula.

The tribromomethansulfonate anion (“tribrate”), [Br3CSO3]−, has been prepared for the first time. The anion is, up to now, the biggest brother of the well-known triflate anion. Key step of the synthesis is the bromination of phenyl-methanesulfonate by KOBr. The new anion could be investigated in the solid state for the example of K[Br3CSO3](H2O).
