Figure 4
Packing views of (II)

, showing (a) the coplanar dimeric units, defining a two-dimensional array. Note the absence of in-plane connections between the dimers. (b) The same view as in (a) but rotated along the vertical axis, disclosing the planarity of the assembly of dimers. Dashed lines indicate hydrogen bonds. [Symmetry code: (i) −x + 1, −y + 2, −z.]
