(E)-2-{4-[1-(Hydroxyimino)ethyl]phenyl­iminomethyl}-6-methoxyphenol mono­hydrate

In the title compound, C(16)H(16)N(2)O(3)·H(2)O, the benzene rings are nearly coplanar with each other, forming a dihedral angle of 4.46 (3)°. There is a strong intra­molecular O—H⋯N hydrogen bond which results in a six-membered ring. In the crystal, the mol­ecules are connected into a three-dimensional network via O—H⋯O and O—H⋯N inter­molecular hydrogen bonds, forming a centrosymmetric ring along the b axis with graph-set motif R (4) (4)(10). In addition, the short distances between the centroids of six-membered rings [3.555 (1) Å], indicate the existence of π–π stacking inter­actions, which may stabilize the crystal structure.
