In addition, C\u2014H...\u03c0 interactions between these ribbons form layers parallel to the (001) plane. Crystal cohesion is ensured by van der Waals interactions between layers. The furan ring and the two thiophene rings are disordered by a 180\u00b0 rotation, with ratios of 0.728\u2005(15):0.272\u2005(15), 0.972\u2005(3):0.028\u2005(3) and 0.791\u2005(3):0.209\u2005(3), respectively.
