Total structure determination of thiolate-protected Au38 nanoparticles.
TLDR
The total structure of Au(38)(SC(2)H(4)Ph)(24) nanoparticles determined by single crystal X-ray crystallography is reported, which is based upon a face-fused Au(23) biicosahedral core and capped by three monomeric Au(SR)(2) staples at the waist of the Au( 23) rod.Abstract:
We report the total structure of Au38(SC2H4Ph)24 nanoparticles determined by single crystal X-ray crystallography. This nanoparticle is based upon a face-fused Au23 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 Au2(SR)3 staples are arranged in a staggered configuration, and the Au38S24 framework has a C3 rotation axis.read more
