In the molecule of the title anthracene derivative, C22H17NO2, the benzene ring is inclined to the mean plane of the anthracene ring system (r.m.s. deviation = 0.024 Å) by 75.21 (9)°. In the crystal, molecules are linked by pairs of O—H...O hydrogen bonds, forming classical carboxylic acid inversion dimers with an R 2 2(8) ring motif. The dimers are linked by C—H...π interactions, forming a supramolecular framework.

In the crystal of the title vanilline derivative, 2C15H15NO4·H2O, the secondary amine molecule is accompanied by half equivalent of water. The molecule is non-planar, with torsion angle Caryl—CH2—NH—Caryl of −83.9 (2)°. In the crystal, the system of O—H...O hydrogen bonds, including bridging water molecules residing on crystallographic twofold axes, results in a two-dimensional layered structure. Within the layers, there are also weak N—H...π interactions involving the vanilline benzene ring.
