The packing in self‐assembled nanocrystal superlattices is determined to a large extent by the geometry of the nanocrystals, as is demonstrated here by the preparation and analysis of wellordered arrays of predominantly tetrahedral silver nanocrystals. The Figure shows the model proposed to explain the monolayer self‐assembly of tetrahedral silver nanocrystals passivated by bundled thiolate molecules.
