7-Chloro-4-[(E)-2-(4-methoxy-benzyl-idene)hydrazin-1-yl]quinoline monohydrate.


ABSTRACT: 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 these chains stack along the a axis via C-H?? and ?-? inter-actions [ring centroid-ring centroid distance = 3.674?(2)?Å]. C-H?O inter-actions are also present.

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 these chains stack along the a axis via C-H⋯π and π-π inter-actions [ring centroid-ring centroid distanc  ...[more]
