2,3,5,6-Tetra-fluoro-1,4-bis-({[(5-methyl-thio-phen-2-yl)methyl-idene]amino}-meth-yl)benzene.


ABSTRACT: The title compound, C20H16F4N2S2, is a flexible bis-thio-phene-type Schiff base ligand with a perfluorinated backbone. The terminal thio-phene rings are almost normal to one another with a dihedral angle of 83.8?(2)°, and they are tilted to the central tetra-fluorinated benzene ring with dihedral angles of 61.2?(2) and 77.7?(1)°. In the crystal, there are ?-? inter-actions involving the benzene ring and the thiophene ring of a symmetry-related molecule with a centroid-centroid separation of 3.699?(3)?Å.

The title compound, C20H16F4N2S2, is a flexible bis-thio-phene-type Schiff base ligand with a perfluorinated backbone. The terminal thio-phene rings are almost normal to one another with a dihedral angle of 83.8 (2)°, and they are tilted to the central tetra-fluorinated benzene ring with dihedral angles of 61.2 (2) and 77.7 (1)°. In the crystal, there are π-π inter-actions involving the benzene ring and the thiophene ring of a symmetry-related molecule with a centroid-centroid separation of 3.69  ...[more]
