Discrete cationic mono(arene) complexes of thallium(I), [Tl(Cp2Fe)]+ and [Tl(C6Me6)]+, were synthesized as [H2N{B(C6F5)3}2]- salts. The Tlâââcentroid distance of 2.723 Å to the arene in [Tl(C6Me6)]+ is the shortest described to date. This remarkably strong arene pi-bonding is confirmed by DFT calculations, which give a Tl-C6Me6 interaction energy of 163 kJ mol-1.
