Figure 4
A packing diagram of (I), showing the hydrogen-bonded tape structure along the b-axis direction. Adjacent tapes, related by a twofold rotation axis, are linked by further C—H⋯O hydrogen bonds, forming wide ribbons parallel to (03). The dashed lines indicate the O—H⋯N and C—H⋯O hydrogen bonds.
