我们报告了通过单晶X射线晶体学确定的AU-38（SC2H4PH）（24）纳米颗粒的总结构。该纳米颗粒基于面部融合的AU-23生物面体核心，该核心由Au23杆的腰部的三个单体AU（SR）（2）钉书钉进一步封闭在底部的Icosahedron上。六个AU-2（SR）（3）主食以交错配置排列，AU38S24框架具有C-3旋转轴。
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.
