Structuring effects of [Ln6O(OH)8(NO3)6(H2O)12]2+ entities

Extending the lanthanide–terephthalate system: Isolation of an unprecedented Tb(III)-based coordination polymer with high potential porosity and luminescence properties

“…However these hexanuclear complexes are required for obtaining this coordination polymer and attempts for obtaining it from a starting simple lanthanide salts failed. This illustrates the so-called ''structuring effect'' of the hexanuclear complexes that have already been observed and described elsewhere [38]. It must be noticed that the powder that has been filtered during the synthesis is amorphous.…”

“…[7,16,17,29- precursor for the construction of new coordination polymers [34][35][36]. In fact, the use of hexanuclear lanthanide-based precursor has been evidenced to have a templating effect on the final compound [37,38]. This molecular precursor even when destroyed is then a useful tool to afford original compounds.…”

A New Series of Anhydrous Lanthanide‐Based Octahedral Hexanuclear Complexes

“…These complexes can be used as molecular precursors for further chemistry. [42,43] However, they still present some slight tendency to hydrolyze, even in dry organic solvents, because of the crystallization and coordination water molecules. In order to increase the chemical stability of the complexes, we thus decided to dehydrate them.…”

Variation of structural motifs in lanthanoid hydroxo clusters by ligand modification

“…The controlled hydrolysis approach to obtain lanthanoid clusters has also been achieved in the absence of protecting ligands. 4,6,[12][13][14][15][16][17] In this case, the pH is slowly raised by the addition of a diluted base (often aqueous NaOH) to the point where the solution becomes persistently turbid. This point is identified as the pH where the equilibrium has reached initial precipitation of lanthanoid hydroxide.…”

“…The inclusion of a para-methoxy group to the ligand, 14H, was found to stabilise a dinuclear motif of composition [Ln 2 (14) 5 ]Cl (Ln = La, Nd, Tb, Dy, Er) (Fig. 17).…”
