Abstract

Reaction of hydrated lanthanide(III) chloride (LnCl3·6H2O) with tris-(2-aminoethyl)amine and the sodium salt of an α-ketocarboxylic acid afforded the trinuclear species [(LnL)2Na]+ which, on removal of Na+, aggregate further in MeOH to yield the neutral eight-co-ordinate cyclic tetranuclear species [Ln4(L1)4] (Ln = YbIII or YIII), and the linear polymer [Y2(L2)2(MeOH)]= with alternating eight- and nine-co-ordinate YIII centres: recrystallisation of adducts of [L1]3– from H2O affords the nine-co-ordinate mononuclear species [Ln(L1)(OH2)2] (Ln = SmIII or GdIII).
