2,3,5,6-Tetra­fluoro-1,4-bis­({[(5-methyl­thio­phen-2-yl)methyl­idene]amino}­meth­yl)benzene

The title compound, C(20)H(16)F(4)N(2)S(2), is a flexible bis­thio­phene-type Schiff base ligand with a perfluorinated backbone. The terminal thio­phene rings are almost normal to one another with a dihedral angle of 83.8 (2)°, and they are tilted to the central tetra­fluorinated benzene ring with dihedral angles of 61.2 (2) and 77.7 (1)°. In the crystal, there are π–π inter­actions involving the benzene ring and the thiophene ring of a symmetry-related molecule with a centroid–centroid separation of 3.699 (3) Å.
