Abstract: The title compound, [Ni(C28H28N4)], crystallizes with two independent molecules 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 24 = 0.043 Å for the first molecule and 0.026 Å for the molecule located on an inversion center. The average Ni-N bond lengths are 1.955 (2) and 1.956 (2) Å in the two molecules. The molecules form - dimers of intermediary strength with a mean plane separation of 3.36 (2) Å.
