Abstract
The central NiII atom in the title complex, [Ni(C16H13BrN2O2)(C5H5N)], is in a square-planar trans-N2O2 environment defined by the NO2 donor atoms of the tridentate hydrazone ligand and the monodentate pyridine ligand. The pyridine molecule forms a dihedral angle of 9.99 (11)° with the least-squares plane through the NiN2O2 atoms.
