The crystal structure of the title compound, [Ni(NO3)(C14H32N4)]NO3, was determined by X-ray diffraction. The Ni-II ion is six-coordinate in a distorted octahedral arrangement, with the tetradentate macrocyclic ligand in a folded conformation. The two five-membered rings of the macrocyclic ligand have skew conformations, while the two six-membered rings adopt chair conformations. The four chiral N-atom centers are 1RS, 4SR, 8RS and 11SR, and the chiral C-atom centers are 5SR and 12SR.
