Crystal structure of boron-rich metal borides - Wikipedia

Metals, and specifically rare-earth elements, form numerous chemical complexes with boron.Their crystal structure and chemical bonding depend strongly on the metal element M and on its atomic ratio to boron. When B/M ratio exceeds 12, boron atoms form B 12 icosahedra which are linked into a three-dimensional boron framework, and the metal atoms reside in the voids of this framework.
