Abstract: In the title compound, [Ni(C₃₈H₃₈N₁₀)](NO₃)₂·2H₂O, the Ni^II ion is located on a crystallographic twofold rotation axis and is in a distorted octahedral coordination environment. The crystal structure is stablized by intermolecular N-HO and C-HO hydrogen bonds, and weak C-H [pi] interactions. The O atoms of the unique nitrate ion are disordered over two sites with occupancies of 0.63 (1) and 0.37 (1). In addition, the O atom of the unique solvent water molecule is disorded over two sites with equal occupancies.
