Figure 2 A packing diagram, illustrating the four heterochiral catemers created by acid-to-ketone H bonds proceeding along chains of mol­ecules glide-related in the 010 direction. The handedness of the mol­ecules is differentiated by the shading of the bonds. Starting at the origin, the order of the directional alignment of the four chains with respect to the c axis is + + - -. Displacement ellipsoids are drawn at the 40% probability level for non-H atoms.
