چکیده
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.

Redetermination of bis(2-formylphenolato-κ2 O,O′)nickel(II) as bis[2-(iminomethyl)phenolato-κ2 N,O′]nickel(II)
The crystal structure of bis-(2-formyl-phenolato-κ(2)O,O')nickel(II), [Ni(C(7)H(5)O(2))(2)], a square-planar centrosymmetric complex, has been reported previously [Li & Chen (2006). Acta Cryst. E62, m1038-m1039]. However, a number of warning signs allows the assumption that the carbonyl group in the salicylaldehydate ligand of the claimed complex is incorrect. The crystal structure was therefor...

The complete mol-ecule of the title complex, [Co(C(14)H(9)Br(2)FNO)(2)], is generated by crystallographic twofold symmetry, with the Co(II) atom lying on the rotation axis. The coordination of the metal atom by the two N,O-bidentate ligands results in a squashed CoN(2)O(2) tetra-hedron. The six-membered chelate ring is an envelope, with the metal atom as the flap. The dihedral angle between the...
