Zinc(II) Complexes with Tetrafluoroterephthalic and Octafluorobiphenyl-4,4′-dicarboxylic Acid Anions and 1,10-Phenanthroline

Resumo

Zinc(II) complexes with 1,10-phenanthroline and tetrafluoroterephthalate and octafluorobiphenyl 4,4′-dicarboxylate anions have been synthesized. According to the IR spectral data, the complexation involves coordination of the metal ion to the nitrogen atoms of phenanthroline and carboxylate oxygen atom of the acid anion. The complexes show photoluminescence in the visible region of the spectrum. The structure of the complex salt [Zn(H₂O)₆][Zn(H₂O)₄(L²)₂] · H₂O, where L² is octafluorobiphenyl-4,4′-dicarboxylate anion (monodentate ligand), has been determined by X-ray analysis.
