摘要：

We report the total structure of Au-38(SC2H4Ph)(24) nanoparticles determined by single crystal X-ray crystallography. This nanoparticle is based upon a face-fused Au-23 biicosahedral core, which is further capped by three monomeric Au(SR)(2) staples at the waist of the Au23 rod and six dimeric staples with three on the top icosahedron and other three on the bottom icosahedron. The six Au-2(SR)(3) staples are arranged in a staggered configuration, and the Au38S24 framework has a C-3 rotation axis.
