Abstract: In the title compound, [Ni(C₆H₁₂N₄O₃)₂](NO₃)₂·4H₂O, the Ni^II cation is located on an inversion center and is N,O,O'-chelated by two nitrilotris(acetamide) molecules in a distorted octahedral geometry. The complex cations, nitrate anions and lattice water molecules are connected by O-HO and N-HO hydrogen bonds, forming a three-dimensional supramolecular structure.
