title: Crystal structure of (E)-2-({[2-(1,3-dioxan-2-yl)phen-yl]imino}-meth-yl)phenol.
abstract: The title compound, C17H17NO3, prepared by the condensation reaction of 2-(1,3-dioxan-2-yl)aniline and salicyl-aldehyde, has an E conformation about the C=N bond. The six-membered O-heterocycle adopts a chair conformation, with the bond to the aromatic ring located at its equatorial position. The dihedral angle between the aromatic rings is 36.54 (9)°. There is an intra-molecular N-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along the a-axis direction. Within the chains, there are C-H⋯π inter-actions involving adjacent mol-ecules.
