Figure 2
A view along the b axis of the crystal packing of I. The intramolecular O—H⋯N and intermolecular C—H⋯O hydrogen bonds are shown as dashed lines, and the C—H⋯π interactions as blue dashed arrows (see Table 2). The coloured double-headed arrows indicate the presence of π–π interactions (naphthalene rings are shown in blue and phenol rings in red). Only the H atoms involved in these interactions have been included. |
