Figure 2
Part of the crystal packing of (I)[link], showing a hydrogen-bonded (dashed lines) chain along the a axis and ππ inter­actions. For clarity, only H atoms involved in the hydrogen bonding are shown. Atoms labelled with the suffixes a, b and c are generated by the symmetry operations (1 + x, y, z), (x − 1, y, z) and (x − 1, [{1\over 2}]y, z[{1\over 2}]), respectively.
