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.
标题配合物[Ni(C₁₄H₁₁FNO)₂]的不对称单元包含半个分子，Ni(II)阳离子位于一个对称中心上，由一个双齿席夫碱阴离子配位。阳离子Ni(II)中心处于扭曲的平面正方形配位环境中，被两个席夫碱配体的亚胺N和酚盐O供体原子螯合。两个配体的N和O供体原子相互反位，Ni-N和Ni-O键长分别为1.9242(10) Å和1.8336(9) Å。氟苯环几乎与配位平面正交，与酚盐环形成的二面角为82.98(7)°。在晶体中，分子通过弱C-H⋯F氢键连接成螺旋链。额外的C-H⋯π接触将分子排列成平行于ac平面的片层。
