description The title compound crystallizes as a hemihydrate, C18H20N2O5�0.5H2O. The molecule exists in an E conformation with respect to the C N imine bond. The 4-methoxyphenyl unit is disordered over two sets of sites with a refined occupancy ratio of 0.54 (2):0.46 (2). The dihedral angles between the benzene rings are 29.20 (9) and 26.59 (9)�, respectively, for the major and minor components of the 4- methoxy-substituted ring. All methoxy substituents lie close to the plane of the attached benzene rings [the Cmethyl—O—C— C torsion angles range from �4.0 (12) to 3.9 (2)�]. In the crystal, the components are linked into chains propagating along [001] via N—H� � �O and O—H� � �O hydrogen bonds and weak C—H� � �O interactions.
