Le corindon (α-Al2O3) a une structure rhomboédrique (groupe d'espace n° 167, notation Strukturbericht D51), dont les paramètres de maille sont

  • a = 5,128 Å ;
  • α = 55,47 °.

Le motif est composé de deux groupements hexaédriques dont la hauteur fait 2,73 Å. Les plan de symétrie de ces hexaèdres sont séparés d'une distance de 7,21 Å.
