In the title compound, [Ni(C11H13N2O4)2]·C3H7NO, the NiII ion is octahedrally coordinated in an N2O4 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 aminoalcohol 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 dimethylformamide (DMF) solvent molecule, while the other links molecules into chains along the b axis through intermolecular O—H⋯O hydrogen bonds. There are bifurcated C—H⋯O interactions involving one of the nitro groups between parallel stacks of molecules in the b-axis direction.

The complex, C25H33N5NiO9, was synthesized by adding a 20 mL solution of nickel nitrate hexahydrate (0.61 gram, 2.63 mmol) to another 20 ml of methanol solution containing 1.25 gram (5.26 mmol) of the ligand, 5-nitrosalicylaldehydene-2,2-dimethyl ethylimine-1-ol. Three drops of triethylamine was added followed by continuous stirring overnight at 40°C. The solution was then filtered, evaporated under vacuum, and washed with ethanol to yield 95% of a dark greenish yellow solid. About 0.20 mg of the sample was dissolved in DMF/MeOH (1:3) then layered with diethyl ether to give dark-yellow–green crystals.
H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with a C—H distances of 0.93 to 0.97 Å and O—H distances of 0.82. Isotropic thermal parameters were Uiso(H) = 1.2Ueq(C) [Uiso(H) = 1.5Ueq(C)].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the title complex two uninegative tridentate ligands, 5-nitro salicylaldehydene-2,2-dimethyl ethylimine-1-ol, coordinate to the nickel atom producing N2O4 in a slightly distorted octahedral coordination environment. The distortion can be justified by the bond angles formed by the coordinating atoms to the metal: N(1 A)—Ni—O(2 A) = 168.90 (8)°, N(1 A)—Ni—O(1B) = 98.60 (8)°, N(1 A)—Ni—O(2B) = 93.54 (8)°, N(1 A)—Ni—N(1B) = 171.23 (8)°, O(1B)—Ni—O(2B) = 167.86° and O(1 A)—Ni—O(2 A) = 168.90 (8)°. The Ni—O bond lengths are slightly shorter than the Ni—N bond lengths [Ni—N(1 A) = 2.038 (2) Å, Ni—N(1B) = 2.0465 (19) Å, Ni—O(2B) = 2.101 (2) Å, Ni—O(2 A) = 2.106 (2) Å] as is usually found in such complexes (Ali et al. 2006; Butcher et al. 1981, 2009; Gultneh et al. 1998; Mustafaa et al. 2009; Zhang et al. 2010).
One of the alcohol H atoms forms a hydrogen bond with the dimethylformamide solvate molecule while the other links the molecules into chains along the b axis through intermolecular O—H···O hydrogen bonds. There are bifurcated C—H···O interactions between parallel stacks of molecules in the b direction involving one of the nitro groups.
