title: Crystal structure of methyl (E)-4-[2-(8-hy-droxy-quinolin-2-yl)vin-yl]benzoate.
abstract: The title compound, C19H15NO3, was synthesized by a Perkin reaction of 2-methyl-8-hy-droxy-quinoline and 4-formyl-2-methyl-benzoate in acetic anhydride under a nitro-gen atmosphere. The mol-ecule has anEconformation about the C=C bond, and the quinoline ring system and the benzene ring are inclined to one another by 29.22 (7)°. There is an intra-molecular O-H⋯N hydrogen bond in the 8-hy-droxy-quinoline moiety. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming inversion dimers with anR22(28) ring motif. The dimers are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming sheets parallel to plane (10-1).
