نبذة مختصرة : The molecular conformation of the title compound is stabilized by an intramolecular O—H⋯O hydrogen bond, forming an S(6) ring motif. Intermolecular N—H⋯N and C—H⋯N hydrogen bonds, as well as N—H⋯π and C—H⋯π interactions create a three-dimensional network in the crystal.
The molecular conformation of the title compound, C20H15Cl2N3O2, is stabilized by an intramolecular O—H⋯O hydrogen bond, forming an S(6) ring motif. The central pyridine ring is almost planar [maximum deviation = 0.074 (3) Å]. It subtends dihedral angles of 86.10 (15) and 87.17 (14)°, respectively, with the phenyl and dichlorophenyl rings, which are at an angle of 21.28 (15)° to each other. The =C(—OH)CH3 group is coplanar. In the crystal, molecules are linked by intermolecular N—H⋯N and C—H⋯N hydrogen bonds, and N—H⋯π and C—H⋯π interactions, forming a three-dimensional network. The most important contributions to the crystal packing are from H⋯H (33.1%), C⋯H/H⋯C (22.5%), Cl⋯H/H⋯Cl (14.1%), O⋯H/H⋯O (11.9%) and N⋯H/H⋯N (9.7%) interactions.
