Tetra-ethyl-ammonium tetra-kis-(1,1,1,5,5,5-hexa-fluoro-acetyl-acetonato)terbate(III).


ABSTRACT: The title compound, (C(8)H(20)N)[Tb(C(5)HF(6)O(2))(4)], is a tetrakis ?-diketonate complex of hexa-fluoro-acetyl-acetone with terbium(III), and tetra-ethyl-ammonium as the counter-ion. This compound shows typical green terbium(III) luminescence upon excitation at about 335?nm. The coordination geometry around the Tb(III) atom is a slightly distorted square anti-prism. One hexa-fluoro-acetyl-acetone ligand has a disordered CF(3) group [occupancies of 0.575?(4) and 0.425?(4)]. A three-dimensional network is built up by linkage of Tb(III) complexes via C-H?F inter-actions.
