Crystal structure and Hirshfeld surface analysis of (Z)-2-amino-4-(2,6-di-chloro-phen-yl)-5-(1-hy-droxy-ethyl-idene)-6-oxo-1-phenyl-1,4,5,6-tetra-hydro-pyridine-3-carbo-nitrile.

ABSTRACT: The mol-ecular conformation of the title compound, C₂₀H₁₅Cl₂N₃O₂, is stabilized by an intra-molecular 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 di-chloro-phenyl rings, which are at an angle of 21.28 (15)° to each other. The =C(-OH)CH₃ group is coplanar. In the crystal, mol-ecules are linked by inter-molecular N-H⋯N and C-H⋯N hydrogen bonds, and N-H⋯π and C-H⋯π inter-actions, 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%) inter-actions.
