There are one and a half independent molecules in the asymmetric unit of the title compound, [Ni(C8H8NO)2], one of which is situated on an inversion center. In both molecules, the NiII ion is coordinated by two O and two N atoms from two Schiff base ligands in an approximate square-planar geometry. Intermolecular N-H...O hydrogen bonds link three molecules into centrosymmetric trimer. The crystal packing exhibits weak intermolecular C-H...O hydrogen bonds and voids of 37 Å3.
