Crystal structure of (E)-N-{2-[2-(2-chloro­benzyl­idene)hydrazin-1-yl]-2-oxoeth­yl}-4-methyl­benzamide monohydrate

The title compound, C17H16ClN3O2·H2O, an acyl-hydrazone derivative, contains a glycine moiety and two substituted benzene rings on either end of the chain. It crystallized as a monohydrate. The mol-ecules adopt an E conformation with respect to the C=N double bond, as indicated by the N-N=C-C torsion angle of 179.38 (14)°. The mol-ecule is twisted in such a way that the almost planar Car-C(=O)-N(H)-C(H2) and C(H2)-C(=O)N(H)-N=C-Car [r.m.s deviations = 0.009 and 0.025 Å, respectively] segments are inclined to on another by 77.36 (8)°, while the benzene rings are normal to one another, making a dihedral angle of 89.69 (9)°. In the crystal, the water mol-ecule links three mol-ecules through two O-H⋯O and one N-H⋯O hydrogen bonds. The mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(14) ring motif. The dimers are linked by O-H⋯O hydrogen bonds, involving two mol-ecules of water, forming chains along [100], enclosing R 2 (2)(14) and R 2 (2)(18) ring motifs. The chains are linked through C-H⋯O inter-actions, forming sheets parallel to (010). Within the sheets, there are C-H⋯π and parallel slipped π-π stacking inter-actions present [inter-centroid distance = 3.6458 (12) Å].
