In the title compound, [Ni(C(11)H(13)N(2)O(4))(2)]·C(3)H(7)NO, the Ni(II) ion is octa-hedrally coordinated in an N(2)O(4) environment by two identical Schiff base ligands. The Ni-O bond lengths range from 2.004 (2) to 2.106 (2) Å, while the Ni-N bond lengths are 2.038 (2) and 2.0465 (19) Å. The cis bond angles range from 78.64 (8) to 97.30 (8)°, with the former being due to the small bite of the amino-alcohol ligand, while the trans bond angles range from 167.86 (8) to 171.23 (8)°. One of the alcohol H atoms forms a hydrogen bond with the dimethyl-formamide (DMF) solvent mol-ecule, while the other links mol-ecules into chains along the b axis through inter-molecular O-H⋯O hydrogen bonds. There are bifurcated C-H⋯O inter-actions involving one of the nitro groups between parallel stacks of mol-ecules in the b-axis direction.
