Crystal structure of 4-[(2-hy-droxy-3-meth-oxy-benz-yl)amino]-benzoic acid hemihydrate.

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