(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 ?-? [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.

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.
