Syntheses and crystal structures of Eu(III) and Sm(III) perrhenate complexes with 2,2′-(imino)bis(N,N′-diethylacetamide)

Abstract

Europium(III) and Sm(III) perrhenate complexes with 2,2 -(imino)bis(N,N -diethyl-acetamide) (IDEA) were synthesized. From the single crystal X-ray analyses, the synthesized complexes were found to be [Eu(IDEA)

Hydration of divalent lanthanides, Sm2+ and Eu2+: A molecular dynamics study with polarizable AMOEBA force field

“…Unfortunately, there are no experimental reports of interaction distances for aqueous Eu 2+ and Sm 2+ to compare to our results directly. However, there are some studies 53–56 of these ions coordinated with a few Oxygens (in different structures) that have distances ranging from 2.5 to 2.7 Å which is close to the QM and AMOEBA values. In addition, if we are to relate the distance of these two ions and Oxygen to Sr 2+ O, as suggested in reference, 57 the distance of Sr 2+ coordinated to 8 Oxygens ranges from 2.6 to 2.68, which fits the range of what was calculated from the present AMOEBA models.…”

Understanding the excited state dynamics and redox behavior of highly luminescent and electrochemically active Eu(iii)–DES complex

“…The k -range considered in the data analysis of the present work, however, does not allow resolution of the features indicating separate Eu–O ligand and Eu–O nitrate scattering paths in Fourier transformed χ ( R ) data. 43 Therefore, oxygen atoms originating from DES and nitrate ions were clubbed together in one shell, indicated as Eu–O (Table 1), in the EXAFS data analysis. The participation of a higher Z back-scatterer is also indicated in the WT transformed data (Fig.…”

“…As per the Eu(III)-DES computationally generated structure (Fig. 5b), oxygen atoms of the nitrate ions participate 43 Therefore, oxygen atoms originating from DES and nitrate ions were clubbed together in one shell, indicated as Eu-O (Table 1), in the EXAFS data analysis. The participation of a higher Z back-scatterer is also indicated in the WT transformed data (Fig.…”
