Bis{2,4-dibromo-6-[(E)-(4-fluoro­benz­yl)imino­meth­yl]phenolato-κ²N,O}cobalt(II)

The complete mol­ecule of the title complex, [Co(C₁₄H₉Br₂FNO)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 CoN₂O₂ tetra­hedron. The six-membered chelate ring is an envelope, with the metal atom as the flap. The dihedral angle between the planes of the aromatic rings within each ligand is 84.1 (6)°.

2-[(E)-(4-Fluoro­benzyl­imino)­meth­yl]-4-methyl­phenol

In the title Schiff base compound, C₁₅H₁₄FNO, the benzene rings make a dihedral angle of 72.75 (13)°. The mol­ecular structure is stabilized by an intra­molecular O—H...N hydrogen bond. In the crystal, weak π–π stacking occurs between the phenol rings of inversion-related mol­ecules, the centroid–centroid distance being 3.7731 (14) Å.

2-[(E)-(4-Fluoro­benz­yl)imino­meth­yl]-6-meth­oxy­phenol

In the title Schiff base, C₁₅H₁₄FNO₂, the dihedral angle between the benzene rings is 53.32 (8)°. In the crystal, mol­ecules related by a twofold rotation axis are linked by pairs of C—H...O hydrogen bonds into dimers with R₂²(18) ring motifs. An intra­molecular O—H...N hydrogen bond is also observed.

N-[(E)-4-Fluoro­benzyl­idene]-3,4-di­methyl­aniline

In the title Schiff base, C₁₅H₁₄FN, the N=C bond length of 1.263 (2) Å is shorter than the N—C bond [1.426 (2) Å], indicating a typical imine double bond. Moreover, the C—N—C angle is 118.5 (2)°. The benzene rings form a dihedral angle of 51.22 (5)°.
