On the Structure of Thiolate-Protected Au.

The article discusses a study on the structure of thio-group(RS)-protected gold nanoparticles using the Density Functional Theory for which experimental determination remains elusive. The physiochemical properties of [Au25(RS)18] and its stability is determined. It is mentioned that the proposed str...

Sumario:The article discusses a study on the structure of thio-group(RS)-protected gold nanoparticles using the Density Functional Theory for which experimental determination remains elusive. The physiochemical properties of [Au25(RS)18] and its stability is determined. It is mentioned that the proposed structure Au2(RS)18 is found to be a compact Au13 core protected by sox [(MeS)3Au2] complexes.
