Figure 3
A stereoview of part of the crystal structure of (I)

, showing the π-stacking of the hydrogen-bonded C(6) chains along (0, y, − $[{1 \over 4}]$ ) and (0, y, − $[{3 \over 4}]$ ) to form part of the π-stacked sheet parallel to (100). Dashed lines indicate hydrogen bonds. For the sake of clarity, H atoms not involved in the motif shown have been omitted.
