Today at IISER-TVM Jemmis gave me a nice overview of his work [see this paper] showing how this and the associated defect structures emerge naturally from several building blocks including B_12 icosahedra which turn out to be particularly stable.

Geometric solid state chemistry
A while ago I posted about the incredibly rich crystal structure of boron which has a unit cell of hundreds of atoms.
Today at IISER-TVM Jemmis gave me a nice overview of his work [see this paper] showing how this and the associated defect structures emerge naturally from several building blocks including B_12 icosahedra which turn out to be particularly stable.
One call also make fruitful analogies with Huckel type rules associated with aromatic molecules such as benzene.
