In the title compound, [Ni(C28H18N2O2)], the Ni-II centre has a square-planar coordination geometry in which the Schiff base ligand acts as a cis-O,N,N ',O'-tetradentate ligand. The crystal structure is built up of centrosymmetric dimer units stacked into chains along the [010] direction. Adjacent chains associate via C-H center dot center dot center dot O hydrogen bonding only, leading to a two-dimensional sheet-like structure consisting of layers parallel to (10 (1) over bar). The cofacial dimeric complex contains an Ni center dot center dot center dot Ni contact of 3.291 (4) angstrom.
