Abstract
Bis(dimethylphosphino)methane (dmpm) was used as a ligand to synthesize four semi-supported dinuclear gold(I) complexes, dmpm(AuR)2 (R = Cl, C6H5, C6Cl5, and C6F5), which were studied concerning the synergistic effects of two weak noncovalent interactions: aurophilic and aryl-aryl stacking interactions. The chloro-substituted complex was synthesized by the ligand substitution of (tht)AuCl with dmpm and further functionalized by the reaction with PhMgBr or in situ-generated C6Cl5Li to afford the phenyl- and pentachlorophenyl-substituted compounds, respectively. The pentafluorophenyl-substituted gold complex was generated by the ligand substitution of (tht)Au(C6F5) with dmpm. All complexes were characterized by multinuclear NMR spectroscopy, CHN analyses, and X-ray diffraction experiments. Additionally, the basic photoluminescence properties of dmpm(AuCl)2, dmpm(AuC6Cl5)2, and dmpm(AuC6F5)2 were examined. The aggregation behavior of dmpm(AuC6F5)2 was further investigated by variable-temperature diffusion-ordered NMR spectroscopy experiments.

Abstract
A new dinuclear cyclic gold(I) complex [Au2(DCyPA)2](PF6)2, 1, based on bis[2-(dicyclohexylphosphano)ethyl]amine (DCyPA) has been synthesized and characterized by elemental analysis, IR and NMR spectroscopy, and X-ray crystallography. In the dinuclear complex cation [Au2(DCyPA)2]2+, the two gold(I) ions are bridged by the ligand bis[2-(dicyclohexylphosphano)ethyl]amine (DCyPA) giving rise to a 16-membered ring centrosymmetric metallacycle. The cytotoxicity of the complex was evaluated against the triple-negative human breast cancer cells MDA-MB-231. In order to understand the mechanism of the cytotoxic behavior, a variety of assays, including Annexin V-FITC/Propidium iodide double staining, ROS production, and mitochondrial membrane potential and migration assays were carried out. The results indicated that complex 1 induced cytotoxicity via an oxidative stress-mediated intrinsic apoptotic pathway in MDA-MB-231 cancer cells.

Abstract
The title compound crystallizes with a trans-O—P⋯P—S geometry of the groups either side of the C=C double bond. The title compound, [AuCl(C26H22OP2S)]·0.5CH2Cl2, crystallizes with a trans-O—P⋯P—S geometry of the groups either side of the C=C double bond, which prevents any intramolecular contact between the Au and O atoms. The AuI atom exhibits a nearly linear coordination [Cl—Au—S = 177.55 (4)°]. The molecules associate to form broad ribbons parallel to the c axis via two C—H⋯O, one C—H⋯Cl(Au) and one Au⋯Cl interaction.
