Surface step structure of Ag13OsO6, experimental evidence for Ag13 cluster building blocks.
The surface of single crystal Ag(13)OsO(6) has been investigated using atomic force microscopy. Growth spirals with very large flat terraces, separated by steps of equal height, have been observed. The measured step height of approximately 6.7 Angstrom corresponds to the diameter of one Ag13-icosahedron and identifies the cluster as the key structural building block.
