Structural effects of trifluoromethylation and fluorination in gold(i) BIPHEP fluorothiolates†
Abstract
We synthesised and characterised two new BIPHEP-bridged digold(I) perfluorothiolates. Experimental and theoretical analyses through the Quantum Theory of Atoms in Molecules revealed that the long-range inductive effects are larger for CF3 than they are for F. Moreover, the aurophilic interaction and F–Au contacts were qualified mostly as covalent and closed-shell type respectively.
