A geminal dithallated bis(iminodiphenylphosphorano)methine carbon bridged dimer bound by Tl–Tl interactions

Abstract

A geminal dithallated bis(iminodiphenylphosphorano)methine carbon complex was prepared and isolated as a solid dimer, stable in an inert atmosphere. It has been fully characterized in both solution and solid states. Bonding has been assessed with the aid of DFT calculations. All data demonstrate that the dimer contains a single carbon center σ bound to two Tl^(I) atoms (Tl^(I)–C–Tl^(I)). Two geminal monomers associate via Tl^(I)–Tl^(I) interactions to form the dimer.
