Packing views of (I)

, showing (a) the coplanar (201) slabs running along [010], composed of type A or type B molecules. Note the absence of in-plane connections between the slabs. (b) The same view as on the left but rotated along the vertical axis, disclosing the planarity of the whole group. Dashed lines indicate hydrogen bonds.
