TLDR
By controlling the ratio of metal ion to ligand concentrations in the DyIII-acetate system, the complexation rate constant for the formation of the bisacetato-complex was found to be significantly larger than for the monoacetato complex as mentioned in this paper.Abstract:

Enhancement of anion binding in lanthanide optical sensors.
TL;DR: It is shown that selected ALs in lanthanide/anion systems greatly improve sensor performance for medical, planetary science, and biodefense applications and is suggested that the observed anion binding enhancement could result from an AL-induced increase in positive charge at the Lanthanide ion binding site.

Metal ion association in alcohol solutions—I: Erbium nitrate association in aqueous methanol
Jeffry Reidler,Herbert B. Silber +1 more
TL;DR: In this paper, the authors investigated the association reaction between erbium(III) and nitrate ion through the use of the ultrasonic relaxation technique in solvent mixtures of methanol and water.

Europium(III) complexation reactions in water
TL;DR: In this article, the inner sphere complexes are present between Eu(III) and NO 3 − in water and a calculated complexation rate constant of 5.4 × 10 8 S −1, a value too large for the formation of the EuNO 3 2+ complex.

A Combination of Factors: Tuning the Affinity of Europium Receptors for Phosphate in Water.
TL;DR: Whereas the affinity of the EuIII complexes for phosphate is substantially influenced by the presence of a single charged group or hydrogen-bond donor, their selectivity for phosphate over competing anions remains unaffected by the addition of the peripheral groups.

Metal ion association in alcohol solutions—VIII: Lanthanide and alkaline earth perchlorates in aqueous methanol
TL;DR: In this paper, ultrasonic absorption measurements in aqueous methanol confirm the existence of outer-sphere complexes between perchlorate and alkaline earth ions between Gd, Nd, Er, and Nd.
