Abstract

In the title compound, C₁₂H₉NO₃, the benzoate and furan rings are almost coplanar, making a dihedral angle of 11.68 (9)°. The twist angle between the -COO group and the benzene ring is only 2.79 (16)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [100]. The mol-ecules stack in a herringbone fashion and inversion-related chains are linked by offset π-π inter-actions [inter-centroid distance = 3.931 (1) Å], forming ribbons propagating along the a-axis direction.

Keywords: 2-furanaldoxime; benzoyloxime ester; crystal structure; hydrogen bonding; oxime.
