Crystal structure of 3-ethynylbenzoic acid
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...
