Magic number C60-Au complexes have been assembled on the Au(111) surface and imaged with the low-temperaturescanning tunneling microscope. These complexes have a unique structure consisting of a single atomic layer Au island encapsulated by a self-selected number, seven, ten, and twelve, e.g., of C60 molecules. The smallest structure consisting of 7 C60 molecules and 19 Au atoms, stable up to 400 K, behaves like a giant molecule with a preferred orientation on the surface. This study uncovers a new strategy for surface-based nano-fabrication with an exceptional high degree of accuracy.
