title: (E)-Benzaldehyde (2,4,6-trichloro-phen-yl)hydrazone.
abstract: The title compound, C(13)H(9)Cl(3)N(2), was obtained from a condensation reaction of benzaldehyde and 2,4,6-trichloro-phenyl-hydrazine. The mol-ecule assumes an E configuration with the phenyl ring and trichloro-phenyl ring located on opposite sides of the C=N bond. The phenyl ring is oriented at a dihedral angle of 42.58 (12)° with respect to the tricholorophenyl ring. In the crystal, the mol-ecules are linked via N-H⋯N hydrogen bonds, forming supra-molecular chains running along the c axis. π-π stacking is present between parallel trichloro-phenyl rings of adjacent mol-ecules, the face-to-face and centroid-centroid distances being 3.369 (14) and 3.724 (2) Å, respectively.
