Crystal structure of (Z)-3-benzyloxy-6-[(2-hydroxyanilino)methylidene]cyclohexa-2,4-dien-1-one

Abstract

In the title compound, C₂₀H₁₇NO₃, the methylidenecyclohexa-2,4-dienone moiety is approximately planar [maximum deviation = 0.0615 (10) Å] and is oriented at diherdral angles of 69.60 (7) and 1.69 (9)° to the phenyl and hydroxybenzene rings, respectively. The amino group links with the carbonyl O atomviaan intramolecular N—H...O hydrogen bond, forming anS(6) ring motif. In the crystal, the molecules are linked by O—H...O hydrogen bonds and weak C—H...O and C—H...π interactions, forming a three-dimensional supramolecular architecture.
