Abstract:
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.
