Аннотация: The structure of symmetrical thiolate cluster Au₂₅(SR)₁₈ becomes asymmetrical after the removal of all bridging S*R groups from the six staple fragments (SR)Au(S*R)Au(SR). This is accompanied by the formation of new Au₃ and Au₄ active sites.

Ключевые слова: gold cluster, geometric structure, catalyst, DFT calculations, relativistic approach.
