摘要
The Voronoi-Dirichlet polyhedra (VDP) and the method of intersecting spheres were used to analyze the oxygen environment of the lanthanum atoms in the structures of 553 compounds containing 763 crystallographically nonequivalent sorts of LaOn polyhedra. The La(III) atoms have a C.N. of 4 to 12 with respect to oxygen. The volume of the VDP of La atoms virtually does not depend on the C.N., although the La-O bond length changes by 0.77 angstrom.
