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

Abstract

In the title compound, C16H16N2O3·H2O, 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 R44(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.
