Figure 3
(a) A packing diagram of (I)[link] along the a axis, indicating the columns of dimers. (b) A packing diagram of (II) along the a axis, indicating the stacks of mol­ecules. (c)/(d) Projections of the crystal packing of (I)[link] and (II), respectively, on the C2/C8/C14 plane of the basic mol­ecule, demonstrating the differences in the mutual orientations of neighbouring mol­ecules. Dashed lines in (c) indicate hydrogen bonds. H atoms (except for the amino H atoms) have been omitted for clarity.
