Crystal symmetries in two supramolecularly initiated morphotropic crystals where the corresponding structures are related by virtual non-crystallographic symmetries. The virtual twofold axes are indicated by dotted lines in (a) space group P21/n (Gruber et al., 2006BB93) and (b) space group P21 (Gruber et al., 2011BB92).
