Bottom Line: The fluoro-phenyl ring is almost orthogonal to the coordination plane and makes a dihedral angle of 82.98 (7)° with the phenolate ring.In the crystal, mol-ecules are linked into screw chains by weak C-H⋯F hydrogen bonds.Additional C-H⋯π contacts arrange the mol-ecules into sheets parallel to the ac plane.

ABSTRACT
The asymmetric unit of the title complex, [Ni(C14H11FNO)2], contains one-half of the mol-ecule with the Ni(II) cation lying on an inversion centre coordinated by a bidentate Schiff base anion. The cationic Ni(II) 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 fluoro-phenyl ring is almost orthogonal to the coordination plane and makes a dihedral angle of 82.98 (7)° with the phenolate ring. In the crystal, mol-ecules are linked into screw chains by weak C-H⋯F hydrogen bonds. Additional C-H⋯π contacts arrange the mol-ecules into sheets parallel to the ac plane.

Mentions: In our previous studies, we reported the syntheses and crystal structures of two related Schiff base complexes, bis­{2-[(E)-(4-fluoro­benz­yl)imino­meth­yl]-6-meth­oxy­phenolato-κ2N,O1}nickel(II) (Bahron et al., 2011 ▶) and bis­{2-[(E)-(4-meth­oxy­benz­yl)imino­meth­yl]phenolato-κ2N,O1}nickel(II) (Bahron et al., 2014 ▶). In this article, we report the successful synthesis of another Schiff base–NiII complex, [Ni(C14H11FNO)2] (1), and its characterization by spectros­copy and elemental analysis. Crystal structure determination confirms the binding mode of the [(4-fluoro­benz­yl)imino­meth­yl]phenolate ligand to the NiII cation (Fig. 1 ▶). The title complex was also tested for anti­bacterial activity, and found to be only weakly active.
