چکیده
In the title compound, C(19)H(18)ClN(3)O(3), the r.m.s. deviation through the 23 non-H and non-meth-oxy atoms is 0.088 Å, indicating a planar mol-ecule with the exception of the meth-oxy groups. One meth-oxy group, surrounded on either side by the other meth-oxy groups, is almost normal to the benzene ring to which it is connected [C-O-C(ar)-C(ar) torsion angle = 81.64 (15)°]. In the crystal, N-H⋯O, C-H⋯O and π-π inter-actions [between quinoline residues; centroid-centroid distance = 3.4375 (8) Å] link mol-ecules into a three-dimensional architecture.

In the title hydrate, C(17)H(14)ClN(3)O·H(2)O, the dihedral angle between the quinoline fused-ring system and the benzene ring is 13.4 (2)° and the conformation about the C=N bond is E. In the crystal, N(h)-H⋯O(w) and O(w)-H⋯N(q) (h = hydro-zone, w = water and q = quinoline) hydrogen bonds generate a two-dimenstional network in the ac plane. A weak C-H⋯O inter-action helps to consolidate the pa...

In the nearly planar title compound (r.m.s. deviation for the 24 non-H atoms = 0.064 Å), C(18)H(16)ClN(3)O(2), the conformation about the N=C bond is E. Supra-molecular chains propagated by glide symmetry along [001] are found in the crystal packing. These are sustained by N-H⋯N hydrogen bonds with the quinoline N atom being the acceptor. The chains are connected into a three-dimensional archit...

The organic mol-ecule in the title hydrate, C(17)H(14)ClN(3)O·H(2)O, has a small but significant twist from planarity, as seen in the dihedral angle of 12.10 (17)° between the quinoline and benzene rings. The conformation about the C=N bond is E. Chains along the b axis are formed in the crystal structure aided by water-quinoline O-H⋯N (× 2) and hydrazone-water N-H⋯O hydrogen bonds. Layers of t...
