Abstract

Reaction in water between trivalent lanthanide ions and ctc 3− ligand leads to [Ln(ctc)(H 2O) 2 · 2.5H 2O] ∞ 3-D molecular networks with Ln = Tb–Yb or Y. These compounds look like molecular precursors for porous solids. Unfortunately, the dehydrated phases are not structurally characterized. We report here the study of the partially dehydrated phases with general formula [Ln(ctc)(H 2O) 2] ∞ with Ln = Tb–Yb or Y obtained by freeze-drying of the corresponding hydrated phases. Their porosity is estimated as well as the luminescent properties of the Tb-containing compound.
