Six fluorinated PR2(biaryl) phosphines, L-n, with R = Ph, Cy and biaryl = C6H4-C6F5, C6F4-C6H5, C6F4-C6F5, have been prepared. Their [AuCl(L-n)] complexes and H congeners with PhJohnPhos or CyJohnPhos have been studied in order to examine the interactions that bring the distal aryl close to the Au-Cl bond region. X-ray, DFT structure optimization, QTAIM, and NCI methods allow for some understanding of the forces involved. The "no bond" noncovalent distal-aryl/Au-Cl weak interactions are produced at forced short distances achieved under intramolecular structural ligand pressure. Enhanced vdW distal-aryl/Au interactions at "no bond" distances shorter than the sum of Au and C vdW radii and weaker distal-aryl/Cl interactions at "no bond" distances beyond the sum of Cl and C vdW radii counterbalance the unfavorable structural distortion of the free ligand, providing some extra stability of the molecule on the order of 2-10 kcal mol(-1). The F substituents in the distal aryl induce shorter aryl distances to the Au-Cl zone, pointing overall to stronger pi-aryl polarization as being mainly responsible for the NCIs with gold. The interactions in the C center dot center dot center dot Cl zone, where the distances are larger than the sum of vdW radii, contribute only about 5%, according to energy estimations using NBOs.
