The title phosphanegold(I) thiol-ate, CHAuFNOPS or [Au(CHFNOS)(CHP)], has the Au centre coordinated by phosphane-P [2.2494 (8) Å] and thiol-ate-S [2.3007 (8) Å] atoms to define a close to linear geometry [P-Au-S = 176.10 (3)°]. The thiol-ate ligand is orientated so that the meth-oxy-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 inter-molecular contacts are discerned with fluoro-benzene-C-H⋯O(meth-oxy) and phenyl-C-H⋯F inter-actions leading to dimeric aggregates. These are assembled into a three-dimensional architecture by phenyl-C-H⋯S(thiol-ate) and phenyl-C-H⋯π(fluorobenzene, phen-yl) inter-actions. 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(fluoro-benzene) and fluoro-benzene-C-H⋯C(imine) inter-actions (-37.2 kcal mol), and from the fluoro-benzene-C-H⋯F and phenyl-C-H⋯O inter-actions (-34.9 kcal mol), the latter leading to the dimeric aggregate.
标题为膦基金(I)硫醇盐,化学式为CHAuFNOPS或[Au(CHFNOS)(CHP)],其中金中心由膦基磷原子[2.2494 (8) Å]和硫醇盐硫原子[2.3007 (8) Å]配位,形成接近线性的几何结构[P-Au-S = 176.10 (3)°]。硫醇盐配体的取向使得甲氧基氧原子指向金原子,形成2.986 (2) Å的Au⋯O近距离接触。在晶体中,可以识别出多种分子间相互作用,包括氟苯-C-H⋯O(甲氧基)和苯基-C-H⋯F相互作用,导致形成二聚体聚集体。这些通过苯基-C-H⋯S(硫醇盐)和苯基-C-H⋯π(氟苯、苯基)相互作用组装成三维结构。因此,对计算得到的Hirshfeld表面的分析表明,所有接触中30.8%是C⋯H/H⋯C类型,但这比H⋯H接触(44.9%)少。表面的其他重要贡献来自H⋯F/F⋯H [8.1%]、H⋯S/S⋯H [6.9%]和H⋯O/O⋯H [3.2%]接触。两个主要的稳定化能量贡献来自苯基-C-H⋯π(氟苯)和氟苯-C-H⋯C(亚胺)相互作用(-37.2 kcal/mol),以及氟苯-C-H⋯F和苯基-C-H⋯O相互作用(-34.9 kcal/mol),后者导致形成二聚体聚集体。
