title: 1-Vinyl-1H-indole-3-carbaldehyde.
abstract: In the title compound, C(11)H(9)NO, the C and O atoms of the attached carbaldehyde group deviate by just 0.052 (2) and 0.076 (1) Å, respectively, from the mean plane of the indole ring system. In addition to van der Waals forces, the mol-ecular packing is stabilized by C-H⋯O hydrogen bonds, which form a C(7) chain motif, and π-π inter-actions (centroid-centroid distance 3.637 Å) between the pyrrole and benzene rings of the indole ring system.
