The title compound, [Ni(C6H4NO2)2(C16H38N6)], was prepared through self-assembly of a nickel(II) aza-macrocyclic complex with isonicotinic acid. The Ni(II) atom is located on an inversion center and exhibits a distorted octa-hedral N4O2 coordination environment, with the four secondary N atoms of the aza-macrocyclic ligand in the equatorial plane [average Ni-Neq = 2.064 (11) Å] and two O atoms of monodentate isonicotinate anions in axial positions [Ni-Oax = 2.137 (1) Å]. Intra-molecular N-H⋯O hydrogen bonds between one of the secondary amine N atoms of the aza-macrocyclic ligand and the non-coordinating carboxyl-ate O atom of the anion stabilize the mol-ecular structure. Inter-molecular N-H⋯N hydrogen bonds, as well as π-π inter-actions between neighbouring pyridine rings, give rise to the formations of supra-molecular ribbons extending parallel to [001].
