Abstract
The molecule of the title compound, C18H18ClN3O4, 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 molecule [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-HO hydrogen bonds as well as C-HCl interactions. The layers stack along the c-axis direction, being connected by C-H.![[pi]](http://scripts.iucr.org/logos/entities/pi_rmgif.gif)
contacts.
