title: Benzyl N-(1-{N'-[(E)-2-chloro-benzyl-idene]hydrazinecarbon-yl}-2-hy-droxy-eth-yl)carbamate.
abstract: The mol-ecule of the title compound, C(18)H(18)ClN(3)O(4), is twisted about the chiral C atom with the dihedral angle between the two amide residues being 87.8 (5)°, but, overall, it can be described as curved, with the benzene rings lying on the same side of the mol-ecule [dihedral angle = 62.8 (4)°]. The conformation about the imine bond [1.294 (7) Å] is E. In the crystal, a two-dimensional array in the ab plane is mediated by O-H⋯O and N-H⋯O hydrogen bonds as well as C-H⋯Cl inter-actions. The layers stack along the c-axis direction, being connected by C-H⋯.π contacts.
