文摘

We report the X-ray structure of a selenolate-capped Au₂₄(SeR)₂₀ nanocluster (R = C₆H₅). It exhibits a prolate Au₈ kernel, which can be viewed as two tetrahedral Au₄ units cross-joined together without sharing any Au atoms. The kernel is protected by two trimeric Au₃(SeR)₄ staple-like motifs as well as two pentameric Au₅(SeR)₆ staple motifs. Compared to the reported gold鈥搕hiolate nanocluster structures, the features of the Au₈ kernel and pentameric Au₅(SeR)₆ staple motif are unprecedented and provide a structural basis for understanding the gold鈥搒elenolate nanoclusters.
