Figure 3
Partial packing diagrams for (a) (I)[link], (b) (II)[link] and (c) (III)[link], showing the pseudo-quadruple hydrogen-bonding motif. H atoms not involved in hydrogen bonding have been omitted for clarity. Only atoms involved in hydrogen bonding (dashed lines) are labelled. [Symmetry codes: (i) −x, −y, −z + 1 for (I)[link]; (i) −x + 2, −y, −z + 2 for (II)[link]; (i) −x, −y, −z + 1 for (III)[link].]
