Abstract Solids containing boron icosahedra have structural elements common to many materials of current interest. For example, a B{sub 60} shell with the same structure as C{sub 60} is part of the structure of elemental boron. The boron-rich solids can thus provide insights into the structural properties of a variety of seemingly unrelated materials. Here scanning tunneling microscopy images of YB{sub 66}(100) are reported that reveal B{sub 156} supericosahedra as discrete structural entities. While the structure of YB{sub 66} is formally described in terms of such supericosahedra, this is the first evidence of their existence as stable units in their own right. {copyright} {ital 1996 The American Physical Society.}
