In the centrosymmetric title compound, [Ni(N3)2(C22H34N6)], the NiII ion is coordinated by the four secondary N atoms of the macrocyclic ligand in a square-planar fashion with two N atoms of the azide ions in axial positions, resulting in a tetragonally distorted octahedron. An N—H⋯N hydrogen-bonding interaction between the secondary amine N atom of the macrocycle and an adjacent azide ion gives rise to a chain structure
