Crystal structure of (E)-pent-2-enoic acid

Crystal structure of (E)-pent-2-enoic acid

The molecule of the title compound, C5H8O2, a low-melting α,β-unsaturated carboxylic acid, is essentially planar [maximum displacement = 0.0239 (13) Å]. In the crystal, molecules are linked into centrosymmetric dimers via pairs of O—H...O hydrogen bonds.
