Bis{2-[(2-hydroxy-2-methylpropyl)iminomethyl]-4-nitrophenolato}nickel(II) dimethylformamide monosolvate

Abstract

In the title compound, [Ni(C 11H 13N 2O 4) 2]·C 3H 7NO, the Ni II ion is octahedrally coordinated in an N 2O 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 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 baxis direction.
