Abstract

The Al subnet in corundum is related to the diamond-like structure of Si. Each Al atom is four-fold coordinated, forming an inverted tetrahedron (umbrella-like). Three Al–Al distances (2.79 Å) are close to those of the parent fcc-Al (2.85 Å), and one has a shorter value of 2.66 Å. Unexpectedly, this cation subnet is similar, in topology and distances, to the 2D diamond-like layers formed by the [Al2]3− polyanions in the Zintl phase Li3Al2 and is also topologically related to the [Al2Si2]2− subnet in CaAl2Si2.
