The molecule of the title compound, [Ni(C68H76N4O4)], is located on a crystallographic inversion center. The Ni—N distances within the square-shaped coordination environment are 1.951 (2) and 1.954 (2) Å. Three terminal C atoms in one of the hexyl groups are disordered over two sets of sites, with site-occupancy factors of 0.615 (13) and 0.385 (13).
