There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

The de novo-predicted and X-ray-confirmed structure of the organic thiol-capped AuAg16(SR)12 cluster. The cluster is comprised of a central icosahedral (AuAg12, made of a gold atom surrounded by twelve silver atoms), capped by four AgS3 mounts, each made of a triangle of sulfur atoms, in yellow, bonded to an anchoring silver atom (black). Each of the twelve sulfur atoms is bonded to an aromatic phenyl ring which is crowned by a tetrabutyl group C(CH3)3. Most of the aromatic rings are organized in dimer bundles (ring dimers pink, red and green) and a cyclic trimer (blue rings), with the rest three rings remaining unbundled (light gray).
