In the title compound, [CuBr(C 16 H 14 Cl 2 N 2 )(C 18 H 15 P)], the coordination polyhedron around the Cu I centre is approximately tetrahedral, distorted by the restricted bite angle of the chelating ligand. Intra-and intermolecular C-HÁ Á Á andstacking interactions are observed.
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
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
The title compound, C 17 H 16 Cl 2 N 2 , adopts a 'vault' conformation. The molecules are linked by a pair of C-HÁ Á ÁN hydrogen bonds into a centrosymmetric dimer with an R 2 2 (18) ring. These dimers are linked by a weak centrosymmetricinteraction into a chain along the [001] direction, and these
