Abstract: The title compound, C25H16OS2, (I), was synthesized via the alkali-catalysed condensation of 3,3'-thenil and 1,3-diphenyl-2-propanone in absolute ethanol. Both 3-thienyl rings in (I) exhibit an 18.89% flip disorder. Thienyl-ring flip disorders are often observed with molecules having unsubstituted terminal 3-thienyl rings [Crundwell et al. (2002). Acta Cryst. E58, o668-o670.
