چکیده
In the title compound, C(24)H(24)N(2)O(4)·H(2)O, the dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base are 65.06 (9) and 3.02 (9)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The H atoms of the water mol-ecule act as donors in the formation of bifurcated O-H⋯(O,O) inter-molecular hydrogen bonds with the O atoms of the hydr-oxy and meth-oxy groups with R(1) (2)(5) ring motifs; these may influence the mol-ecular conformation.
