Artykuł
The copper(II) complexes formed by the herbicide Acifluorfen [5- [2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid] in aqueous solution have been studied by polarographic techniques. The herbicide binds the metal ion acting mainly as a carboxylic ligand, although the simultaneous involvement of the nitro group is suggested by the value of the measured stability constant. Rather insoluble complexes having a dimetallic structure of the tetra^-acetatodiaquadicopper(II) type, as determined by single-crystal X-ray diffraction, precipitate from more concentrated solutions.
