In the title Schiff base complex, [Ni(C(24)H(22)N(2)O(4))], the Ni(II) atom shows a square-planar geometry. The dihedral angles between the central benzene ring and the two outer rings are 4.79 (15) and 7.54 (15)°. In the crystal, mol-ecules are connected through inter-molecular C-H⋯O hydrogen bond, resulting in chains extending along the c axis. The crystal structure is further stabilized by inter-molecular π-π inter-actions, with centroid-centroid distances in the range 3.3760 (15)-3.7196 (17) Å.
