G. Crundwell, T. Meskill, D. Sayers and K. Kantardjieff

Abstract: The title compound, C₁₀H₈O₂S₂, is the 3-thienyl symmetric analog of benzoin. 3,3'-Thenoin can be synthesized in good yield utilizing the benzoin condensation reaction (starting with 3-thiophenecarboxaldehyde). The crystal structure of 3,3'-thenoin has been determined at room temperature. There are two independent molecules per asymmetric unit and each has a thienyl ring flip disorder involving one of the two rings in each molecule.
