Voronoi polyhedra for Sb atoms in the antimony sublattice: (a) Sb1 in [alpha]-Sb2O3 and Sb1 in [beta]-Sb2O3; (b) Sb1 and Sb2, and (c) Sb3 and Sb4 in [gamma]-Sb2O3. 12 grey Sb atoms form a distorted cuboctahedral environment; yellow distant Sb atoms give rise to additional minor faces of the Voronoi polyhedra due to the sublattice distortion. This figure is in colour in the electronic version of this paper.  [article HTML]
