3,4-Dinitro-2,5-bis-[4-(trifluoro-meth-yl)phen-yl]thio-phene.


ABSTRACT: The title compound, C(18)H(8)F(6)N(2)O(4)S, is a precursor for the production of low-band-gap conjugated polymers. In the crystal structure, the dihedral angles between the thio-phene and benzene rings are 35.90?(8) and 61.94?(8)°, and that between the two benzene rings is 40.18?(8)°. The two nitro groups are twisted with respect to the thio-phene ring, the dihedral angles being 53.66?(10) and 31.63?(10)°. Weak inter-molecular C-H?O hydrogen bonding helps to stabilize the crystal structure.
