The asymmetric unit of the title compound, [Ni(C15H14NO2)2], comprises an NiII cation, lying on an inversion centre, and a Schiff base anion that acts as a bidentate ligand. The NiII cation is in a square-planar coordination environment binding to the imine N and phenolate O atoms of the two Schiff base ligands. The N- and O-donor atoms of the two ligands are mutually trans, with Ni—N and Ni—O bond lengths of 1.9191 (11) and 1.8407 (9) A ° , respectively. The plane of the methoxybenzene ring makes a dihedral angle of 84.92 (6)� with that of the phenolate ring. In the crystal, molecules are linked into screw chains by weak C—H� � �O hydrogen bonds. Additional C—H� � �O hydrogen bonds, together with C—H� � �� contacts, arrange the molecules into sheets parallel to the ac plane.
