title: Crystal structure of ethyl 2-(2-{(1E)-[(E)-2-(2-hy-droxy-benzyl-idene)hydrazin-1-yl-idene]meth-yl}phen-oxy)acetate.
abstract: In the title compound, C18H18N2O4, the planes of the benzene rings are twisted with respect to each other at 27.25 (7)°. The mol-ecule displays an extended conformation with an intra-molecular O-H⋯N hydrogen bond. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming supra-molecular chains running along the b-axis direction.
