Figure 15
Unit-cell diagrams viewed down the b-axis showing a superposition (by least-squares fit as described in Fig. 13[link]) of different layers of the α- and α′-polymorphs: (a) the BC layers, which are relatively unchanged in the α- (orange) and α′-polymorphs (black) ; (b) and (c) the lower and upper AA layers, respectively, showing a shift of ca 2.7 Å of the α′-OETCA molecules relative to the α-AA layer (labeled X).
