[4-Bromo-2-[2-(5-bromo-2-oxidobenzylideneaminomethyl)phenyliminomethyl]phenolato-kappa4O,N,N',O']nickel(II).

In the title complex, [Ni(C 21 H 14 Br 2 N 2 O 2 )], the Ni II atom is coordinated by the two imine N and two phenolate O atoms of the Schiff base ligand in a tetrahedrally distorted square-planar geometry. The Ni-N and Ni-O distances are within the ranges expected for Ni-Schiff base derivatives. Intermolecular C-H...O hydrogen bonds link the molecules into centrosymmetric dimers, forming R 2 2 (12) (A) and R 2 2 (10) (B) rings. These dimers combine to form a supramolecular ABAB... aggregate which propagates along the [100] direction.
