Abstract
Mr =160.2, monoclinic, P21/c, a=5.701 (2), b= 18.613(4). c = 7.473 (3) Å, β= 97.57(3)°, V=786.0Å3, Z = 4, Dx= l.35gcm-3, MoKα, λ-0.7107 Å, μ-3.31 cm-1, F(OO0) = 328, room temperature, R=0.050 for 929 reflections with |Fα| > 4σ(|Fα|). The two planar parts in the molecule, the thiophene ring and the dicyanovinyl moiety, are inclined at 3.6(5)D to one another and the vinylic H atom is trans with respect to the S atom. The electron-withdrawing properties of the cyanide groups affect two of the C-C bond lengths.
