Seven La(III) complexes with the β-diketonate anion 4,4,4-trifluoro-1-(2-naphthyl)butane-1,3-dionato(1-) (ntfa) have been synthesized, namely: [La(ntfa)3(MeOH)3] (1a), [La(ntfa)3(H2O)2(EtOH)](EtOH) (1b), [La(ntfa)3(bipy)2] (2), [La(ntfa)3(Me2bipy)] (3), [La(ntfa)3(terpy)] (4), (NEt4)[La(ntfa)4] (5) and [La(ntfa)4Na(H2O)(EtOH)(Methyl-β-naphthylketone)] (6), where bipy = bipyridine, Me2bipy = 5,5′-dimethyl-bipyridine, terpy = terpyridine, NEt4+ = tetraethylammonium ion and structurally characterized. The tris-β-diketonate compounds 1a,b, 2–4 form neutral monomeric complexes with C.N. nine for 1a, 1b and 4, eight for 3, and ten in case of 2. The tetrakis-β-diketonato complexes 5 and 6 have coordination number eight.
