Crystal structure and charge density analysis of the high-pressure boron phase γ-B28

What is it about?

The peculiar bonding situation in γ boron is characterized by a topological analysis of the electron-density distribution revealing one-electron–two-center bonds connecting neighboring icosahedral B12 clusters.

Why is it important?

A unique polar-covalent two-electron–three-center bond between a pair of atoms of an icosahedral cluster and one atom of the interstitial B2 dumbbell is discussed.
