Perspective view of (I), with the atom-numbering scheme. Displacement ellipsoids are at the 50% probability level.
In the title compound, C 7 H 4 ClNO 4 , the molecules form centrosymmetric dimers through OΓHΓ Γ ΓO hydrogen bonds. The dimers are connected by CΓHΓ Γ ΓO hydrogen bonds to form molecular tapes. Disorder of the H atom in the OΓ HΓ Γ ΓO hydrogen bond is suggested.
The crystal structure of the title compound, (I), indole-3-carboxaldehyde was refined to R(F) = 0.053 from room-temperature diffraction measurements (Golubev & Kondrashev, 1984). This re-refinement represents an improvement; all H atoms were located and refined. In the crystal structure, the molecul
