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.
