Figure 13
Average structure of the α phase of P.O.13. View direction [010]. (a) Overall structure, with symmetry elements (space group Pbcn). (b). First single layer, with symmetry elements (layer group P2/c). All symmetry elements of the layer group are crystallographic ones of Pbcn. Molecules in position A are drawn in element colours, those in position C in yellow. (c) Second single layer. Molecules in position B are drawn in pink, in position D in green. |
