Abstract

The title phosphanegold(I) thiolate, C26H22AuFNOPS or [Au(C8H7FNOS)(C18H15P)], has the AuI centre coordinated by phosphane-P [2.2494 (8) Å] and thiolate-S [2.3007 (8) Å] atoms to define a close to linear geometry [P—Au—S = 176.10 (3)°]. The thiolate ligand is orientated so that the methoxy-O atom is directed towards the Au atom, forming an Au...O close contact of 2.986 (2) Å. In the crystal, a variety of intermolecular contacts are discerned with fluorobenzene-C—H...O(methoxy) and phenyl-C—H...F interactions leading to dimeric aggregates. These are assembled into a three-dimensional architecture by phenyl-C—H...S(thiolate) and phenyl-C—H...π(fluorobenzene, phenyl) interactions. Accordingly, the analysis of the calculated Hirshfeld surface shows 30.8% of all contacts are of the type C...H/H...C but this is less than the H...H contacts, at 44.9%. Other significant contributions to the surface come from H...F/F...H [8.1%], H...S/S...H [6.9%] and H...O/O...H [3.2%] contacts. Two major stabilization energies have contributions from the phenyl-C—H...π(fluorobenzene) and fluorobenzene-C—H...C(imine) interactions (−37.2 kcal mol−1), and from the fluorobenzene-C—H...F and phenyl-C—H...O interactions (−34.9 kcal mol−1), the latter leading to the dimeric aggregate.
