Figure 7
R²₂(8) ring pattern resulting from a head-to-tail acid/amide association and its modification, the R²₂(12) ring, which involves the benzoyl carbonyl as an acceptor (BOH1). The two chains of rings are further connected by hydrogen bonds to form the (010) layer perpendicular to the 20 Å direction. Phenyl groups that stick out of the layer are engaged in sandwich-stacking interactions.
