title: (E)-1-(4-Methyl-phen-yl)ethanone [8-(trifluoro-meth-yl)quinolin-4-yl]hydrazone.
abstract: In the title compound, C(19)H(16)F(3)N(3), the dihedral angle between the naphthalene and quinoline ring systems is 14.58 (8)°. The hydrazone C-N-N=C-C chain is in an extended conformation and its mean plane is nearly coplanar with the quinoline plane [dihedral angle = 3.45 (9)°]. The bond angles within the phenyl ring show the almost additive influence of the two para substituents. In the crystal, weak π-π [centroid-centroid distances = 3.779 (2) and 3.718 (1) Å] and C-H⋯F directional inter-actions join the mol-ecules into centrosymmetric dimers, which are further connected into infinite zigzag chains propagating along a.
