Abstract
The title compound, 2-thiophenecarboxylic acid, crystallizes in the monoclinic space group P21/c with unit cell parameters a = 5.698(1) Å, b = 5.043(1) Å, c = 19.712(2) Å, β = 98.49(1)°, Z = 4; Dx = 1.519 Mg m−3. The structure was solved by direct-methods and refined by a full-matrix least-squares procedure on 958 reflections to final R = 0.034. The S(1) – C(2) and S(1) – C(5) bond distances are 1.707(2) Å and 1.695(2) Å respectively. In the crystal lattice the molecules associate via the carboxylic acid groups to form centrosymmetric dimers.
