Synthesis and crystal structure of (E)-N-[(2-bromophenyl)methylidene]-3,5-bis(trifluoromethyl)aniline

The title compound C 15 H 8 BrF 6 N, was prepared by a condensation reaction of 2-bromobenzaldehyde and 3,5-bis(trifluoromethyl)aniline in the presence of anhydrous magnesium sulfate. The compound readily crystallizes from a concentrated hexanes solution in high yield. The imine bond is nearly planar with the 2-bromophenyl group, while the N -(3,5-bis(trifluoromethyl)phenyl moiety is significantly twisted from the imine group [49.61 (5)°]. The crystal packing involves short intermolecular C—H...Br contacts linking zigzag ribbons flanked by fluorous layers.
