Abstract

The synthesis and characterization by single-crystal X-ray diffraction of two thallium salts of the non-co-ordinating anion [B{3,5-(CF₃)₂C₆H₃}₄] are reported. They possess Tl–Tl contacts supported by Tl–aryl interaction. This cation association overcomes both electrostatic repulsion and cation–anion size and charge matching considerations in the [LTl₂L]²⁺ dications so formed.
