Nothing really. but the question was about boron, and that is as easy to look up as any other atom.

I am an experimentalist, however, and have done a bit of work with x-rays and on magnetism.

What you say about boron makes my head spin. As soon as you start talking about bonds, hopping and mixed valence you HAVE to use QM. There is no way around it. But when you look at the electronic properties, the difference between 11B and 10B should not matter so much. BTW, I vaguely recall that icosahedra form the basis of quasicrystals, but are "forbidden" in ordinary crystals?!?
