We explore herein the supramolecular interactions that control the crystalline packing in a series of fluorothiolate triphenylphosphine gold(I) compounds with the general formula [Au(SRF)(Ph3P)] in which Ph3P = triphenylphosphine and SRF = SC6F5, SC6HF4-4, SC6F4(CF3)-4, SC6H3F2-2,4, SC6H3F2-3,4, SC6H3F2-3,5, SC6H4(CF3)-2, SC6H4F-2, SC6H4F-3, SC6H4F-4, SCF3, and SCH2CF3. We use for this purpose (i) DFT electronic structure calculations and (ii) the quantum theory of atoms in molecules and the non-covalent interactions index methods of wave function analyses. Our combined experimental and computational approach yields a general understanding of the effects of ligand fluorination in the crystalline self-assembly of the examined systems, in particular, about the relative force of aurophilic contacts compared with other supramolecular interactions. We expect this information to be useful in the design of materials based on gold coordination compounds.

通过配体氟化作用指导三苯基膦硫醇盐中的晶体堆积。

我们在本文中探索了控制一系列具有通式[Au(SR F)(Ph 3 P)]的氟代硫代三苯基膦金(I)化合物中晶体堆积的超分子相互作用,其中Ph 3 P =三苯基膦,SR F = SC 6 F 5,SC 6 HF 4 -4,SC 6 F 4(CF 3)-4,SC 6 H 3 F 2 -2,4,SC 6 H 3 F 2 -3,4,SC 6 H 3 F 2 -3,5,SC 6H 4(CF 3)-2,SC 6 H 4 F-2,SC 6 H 4 F-3,SC 6 H 4 F-4,SCF 3和SCH 2 CF 3。为此,我们使用(i)DFT电子结构计算和(ii)分子中原子的量子理论以及波函数分析的非共价相互作用指数方法。我们的实验和计算方法相结合,可以对配体氟化在所检查系统的晶体自组装中的作用有一个一般性的了解,尤其是与其他超分子相互作用相比,亲金接触的相对力。我们希望该信息对基于金配位化合物的材料设计有用。
