The title compound, [Ni(C(28)H(28)N(4))], crystallizes with two independent mol-ecules in the unit cell, one of which is located on an inversion center. Both macrocycles exhibit a planar conformation with average deviation from the least-squares-plane of the 24 macrocycle atoms of Δ24 = 0.043 Å for the first mol-ecule and 0.026 Å for the mol-ecule located on an inversion center. The average Ni-N bond lengths are 1.955 (2) and 1.956 (2) Å in the two mol-ecules. The mol-ecules form π-π dimers of inter-mediary strength with a mean plane separation of 3.36 (2) Å.
