Crystal structure of 3-ethynylbenzoic acid

Résumé

In the title compound, C9H6O2, the carb­oxy­lic acid group is almost in the plane of the benzene ring, making a dihedral angle of 2.49 (18)°. In the crystal, mol­ecules are linked by pairs of O-H...O hydrogen bonds, forming classical acid-acid inversion dimers, with an R22(8) ring motif. The dimers are linked by pairs of C-H...O hydrogen bonds forming chains, enclosing R22(16) ring motifs, propagating along the c-axis direction.
