| Popis: | Here we present the crystal structure, experimental and theoretical characterization of a Au-24(SAdm)(16) nanomolecule. The composition was verified by X-ray crystallography and mass spectrometry, and its optical and electronic properties were investigated via experiments and first-principles calculations. Most importantly, the focus of this work is to demonstrate how the use of bulky thiolate ligands, such as adamantanethiol, versus the commonly studied phenylethanethiolate ligands leads to a great structural flexibility, where the metal core changes its shape from five-fold to crystalline-like motifs and can adapt to the formation of Au24+/-1(SAdm)(16), namely, Au-23(SAdm)(16), Au-24(SAdm)(16), and Au-25(SAdm)(16). The basis for the construction of a thermodynamic phase diagram of Au nanomolecules in terms of ligands and solvent features is also outlined. |
