title: (E)-Methyl 3-(4-ethyl-phen-yl)-2-{2-[(E)-(hy-droxy-imino)-meth-yl]phen-oxy-meth-yl}acrylate.
abstract: In the title compound, C(20)H(21)NO(4), the two benzene rings are almost perpendicular to each other, making a dihedral angle of 86.1 (7)°. The hy-droxy-ethanimine group is essentially coplanar with the benzene ring, the largest deviation from the mean plane of the hy-droxy-ethanimine [C=N-OH] group being 0.011 (1) Å for the O atom. An intra-molecular C-H⋯O hydrogen bond occurs. The mol-ecules are linked into cyclic centrosymmetric R(2) (2)(6) dimers via O-H⋯N hydrogen bonds. Inter-molecular C-H⋯O hydrogen bonds link the mol-ecules, forming a C(8) chain along the a axis. The crystal packing is further stabilized by C-H⋯π inter-actions.
