In this work we report some examples of fluorinated lanthanide complexes, in which the geometry of the coordination sphere is controlled by C-F center dot center dot center dot pi system strong interactions involving the fluorinated ligands.

Abstract

In this work we report some examples of fluorinated lanthanide complexes, in which the geometry of the coordination sphere is controlled by C-F center dot center dot center dot pi system strong interactions involving the fluorinated ligands. Moreover we have also shown that a perfluorinated ligand, such as tris(pentafluorophenyl)phosphine oxide may have a role in increasing the pumping of energy, in the Er3+ complex with totally fluorinated ligands, from the pi system of the perfluorinated acetylacetone ligand, acting as antenna, to the Er3+ emitting ion.
