A series of gold(i) phosphine complexes of the type [AuCl{PR 2(Rf)}] (R = Et, i-Pr, Cy; Rf = CFCF 2; R = Ph, Rf = CFCFH, CClCF2, CCCF 3, CF3, i-C3F7, s-C 4F9) have been prepared and most have been structurally characterised. All of the complexes are monomeric in the solid state, and a number of secondary interactions are observed - including short intramolecular Au...F distances, metal-bound Au-Cl...H non-classical hydrogen bonds, fluorous domains and phenyl embraces. Only in the case of [AuCl{PEt 2(CFCF2)}] is an aurophilic interaction with an Au...Au contact less than the sum of the van der Waals radii observed. Even then, the distance, 3.3458(10) A, is longer than that previously observed for the related complex with R = Ph; Rf = CFCF2.
