The asymmetric unit of the title complex, [Ni(C14H11FNO)2], contains one-half of the molecule with the NiII cation lying on an inversion centre coordinated by a bidentate Schiff base anion. The cationic NiII center is in a distorted square-planar coordination environment chelated by the imine N and phenolate O donor 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 1.9242 (10) and 1.8336 (9) Å, respectively. The fluorophenyl ring is almost orthogonal to the coordination plane and makes a dihedral angle of 82.98 (7)° with the phenolate ring. In the crystal, molecules are linked into screw chains by weak C—H...F hydrogen bonds. Additional C—H...π contacts arrange the molecules into sheets parallel to the ac plane.
