Golden Crown
A giant, crown-like Au36 ring aggregate with continuous metal-metal contacts (see picture; gold(I) centers are in ball and stick representation) is formed by an Au(I)-Au(I) bonding interaction directed self-assembly. (c) Wiley-VCH 2008

Chinese researchers have recently made a “golden crown” with a diameter of only a few nanometers. It is a large ring-shaped molecule containing 36 gold atoms. The lords of the ring, a team of researchers from the Universities of Beijing, Hong Kong, and Nanjing report their unusual compound in the journal Angewandte Chemie: the molecular ring structure is held together exclusively by gold–gold bonds and is thus the largest ring system made of gold atoms produced to date.
