3,4-Dimeth-oxy-benzaldehyde [2,8-bis-(trifluoro-meth-yl)quinolin-4-yl]hydrazone.

In the title compound, C(20)H(15)F(6)N(3)O(2), the quinoline ring system is almost coplanar with the benzene ring; the dihedral angle between the two planes is 2.31 (8)°. The crystal structure displays an inter-molecular C-H⋯F hydrogen bond. In addition, a weak π-π inter-action is observed between the unfused benzene ring and the benzene ring of quinoline, with a centroid-centroid distance of 3.586 (1) Å.
