Methyl (E)-2-({2-[(E)-(hy-droxy-imino)-meth-yl]phen-oxy}meth-yl)-3-phenyl-acrylate.

In the title compound, C18H17NO4, the hy­droxy­ethanimine group is essentially coplanar with the ring to which it is attached [C—C—N—O torsion angle = 179.94 (14)°]. The mol­ecules are linked into cyclic centrosymmetric R22(6) dimers via O—H⋯N hydrogen bonds and the crystal packing is further stabilized by C—H⋯O inter­actions.
