Figure 4
A packing diagram of the title compound, showing hydrogen-bonded acid-base units stacked along the b axis via the π–π interactions (magenta dashed lines). The π–π interactions including the centroid of the C11–C16 ring of the base (Cg3) are omitted for clarity. The O⋯H⋯O and C—H⋯O hydrogen bonds are indicated by green dashed lines.
