Abstract

Synthesis and spectroscopic characterization of new lanthanide complexes [Ln(Q(AD))(3)(EtOH)(H2O)], (Ln = Tb, Eu; HQ(AD) = 1-phenyl-3-methyl-4-adamantylcarbonyl-pyrazol-5-one), [H3O][Tb(Q(AD))(4)] [Ln(Q(AD))(3)(N-N)] (Ln = Tb, Eu; N-N = 1,10-phenanthroline (Phen), 2,2'-bipyridyl (Bipy), 4,4'-dimethyl-2,2'-bipyridyl (4,4'-Me(2)Bipy)) are reported. The crystal structures of the proligand HQ(AD) and of complexes [H3O][Tb(Q(AD))(4)] and [Tb(Q(AD))(3)(4,4'-Me(2)Bipy)] have been determined. In both complexes the lanthanide ions are in a square antiprismatic environment, the H3O+ cation in the former acid complex being stabilized by H-bonding. Luminescence studies have been performed on selected derivatives. (c) 2006 Elsevier B.V. All rights reserved.
