Abstract: The relationship between the crystallographic orientation of anionic coordination polyhedra and the surface structures was discussed in this paper. It is suggested that the surface structures show the locus formed by the combination of growth units of anionic coordination polyhedra on different surfaces during crystal growth. Therefore the growth mechanism could be studied and the crystal orientation determined by means of the surface structures in crystals.
