(E)-2-[(4-Ethoxyphenyl)iminomethyl]-4-methoxyphenol

Abstract

In the molecule of the title compound, C16H17NO3, the aromatic rings are oriented at a dihedral angle of 29.25 (8)degrees. An intramolecular O-H center dot center dot center dot N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034 (13) angstrom] six-membered ring, which is oriented at dihedral angles of 0.91 (1) and 28.91 (12)degrees with respect to the aromatic rings. The title molecule is a phenol-imine tautomer, as evidenced by C-O, C-N and C-C bond lengths. In the crystal, molecules are linked by intermolecular C-H center dot center dot center dot O hydrogen bonds that generate C(8) chains.
