چکیده
In the title Schiff base compound, C21H19NO3, the conformation about the C=C bond is Z. The N-H group and carbonyl O atom form an intra-molecular N-H⋯O hydrogen bond with an S(6) ring motif. The benz-yloxy ring and the 2-hy-droxy-5-methyl-phenyl ring are inclined to the central six-membered ring by 13.68 (9) and 9.13 (8)°, respectively, and to one another by 21.95 (9)°. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming helical chains along [010].

The mol-ecule of the title compound, C(16)H(11)N(3)O(3), exists in the keto form and the C=O and N-H bonds are mutually cis in the crystal structure. There are two crystallographically independent mol-ecules per asymmetric unit with broadly similar structural data. The only noticeable difference between the two is the dihedral angles between the benzene and the quinoline rings: 1.04 (4) and 3.0...
