چکیده
The title Schiff base compound, C(20)H(14)ClNO(2), adopts an E configuration about the azomethine bond. The phenol and chloro-benzene rings form dihedral angles of 84.71 (9) and 80.70 (8)°, respectively, with the phenyl ring and are twisted by 15.32 (8)° with respect to one another. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, which forms an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming columns parallel to the a axis.
