Notes:
The structures of five complexes of fluorine-containing bidentate salicylideneamine Schiff base ligands are reported. These are the bis-ligand copper(II) complexes of the Schiff bases derived from salicylaldehyde and 4-fluoro-, [Cu(C13H9FNO)2], 3-fluoro-4-methyl-, [Cu(C14H11FNO)2], 3,5-bis(trifluoromethyl)-, [Cu(C15H8F6NO)2], and 4-trifluoromethoxyanilines, [Cu(C14H9F3NO2)2], and the bis-ligand oxovanadium(IV) complex of the Schiff base derived from salicylaldehyde and 4-trifluoromethoxyaniline, [VO(C14H9F3NO2)2]. Three of the copper complexes have square-planar coordination at the metal, imposed by the virtue of symmetry, but the immediate coordination environment of the copper in the 3,5-bis(trifluoromethyl) complex is intermediate between square planar and tetrahedral. The coordination environment at the metal of the vanadium complex can be described as distorted square pyramidal.
