Abstract: We report the first synthesis of high-purity and high-yield Au25 clusters protected by the basic pyridyl ethanethiol (HSCH2CH2Py, 4-PyET and 2-PyET). Single-crystal X-ray diffraction of the [Au25(4-PyET)18]−·Na+ clusters has revealed a structure similar to that known for the phenyl ethanethiolate analog, but with pyridyl-N coordination to Na+, a more relaxed ligand shell, and a profoundly layered arrangement in the solid state. Because of the pendant Py moiety, the [Au25(4-PyET)18]− clusters are endowed with a unique (de)protonation equilibria, which has been characterized in detail by UV-vis absorption and 1H-NMR spectroscopy. [Au25(4-PyET)18]− clusters showed an unexpectedly H+-dependent solubility that is tunable in aqueous and organic solvents. The successful synthesis of the basic Py-terminated thiolate-protected Au25 clusters paves the way to realize a new family of metalloid clusters possessing basic properties.
