The title compound, C36H50S4, lies about an inversion centre and the four thiophene rings are nearly coplanar. The outer rings are tilted by 3.6 (5)° from the inner rings. Each decyl chain is in the trans conformation and all C atoms are nearly coplanar. The dihedral angle between the aliphatic plane defined by C41—C47 and the thiophene ring plane is 8.6 (1)°. There is slight disorder of the last three atoms of each decyl chain and all those of the outer thiophene rings, with occupancy factors of 65:35.
