Scandium, yttrium and heavy rare-earth elements (Gd-Lu) can form a variety of rare-earth boron compounds. When rich in boron, they often have complex crystal structures where boron icosahedra B12 are interconnected in various
three-dimensional boron frameworks which accommodate metal atoms in their voids. Such structures are reviewed in this article.
