Tetraethylammonium tetrakis(1,1,1,5,5,5-hexafluoroacetylacetonato)terbate(III)

Abstract

The title compound, (C8H20N)[Tb(C5HF6O2)4], is a tetrakis β-diketonate complex of hexafluoroacetylacetone with terbium(III), and tetraethylammonium as the counter-ion. This compound shows typical green terbium(III) luminescence upon excitation at about 335 nm. The coordination geometry around the TbIII atom is a slightly distorted square antiprism. One hexafluoroacetylacetone ligand has a disordered CF3 group [occupancies of 0.575 (4) and 0.425 (4)]. A three-dimensional network is built up by linkage of TbIII complexes via C—H...F interactions.
