title: Bis(2-thien-yl)acetyl-ene.
abstract: The planar [maximum deviation 0.0066 (4) Å] symmetrical mol-ecule of the title compound, C(10)H(6)S(2), lies across a crystallographic inversion centre. The thio-phene rings are rotationally disordered about the acetyl-ene bond, with the two pseudo inversion-related S atoms in 0.80:0.20 occupancy sites. The C C bond distance is 1.195 (9) Å.
