The molecule of the title compound, C 13 H 10 Cl 2 N 2 , is nearly planar and adopts an E conformation about the carbonnitrogen double bond. The dihedral angle between the two benzene rings is 6.70 (13) . Molecules are interconnected through weak N-HÁ Á Á interations.
The asymmetric unit of the title compound, C 14 H 10 Cl 2 N 2 O, comprises two independent molecules, in which the dihedral angles between the terminal phenyl and substituted benzene rings are 21.28 (10) and 39.60 (12) . N-HÁ Á ÁO, C-HÁ Á ÁO and C-HÁ Á ÁCl hydrogen bonds stabilize the conformations
The title compound, C~13~H~8~Cl~3~N~3~O, was synthesized by the condensation reaction of 2,4-dichlorobenzaldehyde with 6-chloronicotinic acid hydrazide in a methanol solution. The Schiff base molecule displays a __trans__ configuration with respect to the C=N and C—N bonds. The dihedral angle betwee
In the original paper by Qiu, Yang, Liu & Zhu [__Acta Cryst.__ (2006), E**62**, m1320–m1231], the H atoms attached to N1 and N3 are positioned incorrectly. These have been deleted and the structure rerefined. The correct name of the structure is bis(2,4-dichlorobenzaldehyde 2-hydroxybenzoylhydrazona
