Europium chloride was prepared by dissolving Europium(III) oxide in excessive 6 mol/L HC1, then hydrated europium chloride was obtained by evaporating away excess HC1 from the solution.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. When heated to decomposition it emits very toxic fumes of Cl-. See also RARE EARTHS.

Formation and dissociation kinetics of Eu(III) complexes with H5do3ap and similar dota-like ligands

Complexation kinetics of the europium(III)-H5do3ap complex (1,4,7,10-tetraazacyclododecane-1,4,7-triacetic-10-(methylphosphonic acid)) was studied at 25 °C and I = 0.1 M KCl and compared with the analogous H4dota-like ligands. The mechanism of the formation reactions between the europium(III) ion and H3do3a, H4dota and H4dota analogs having one methylphosphonic (H5do3ap) or phosphinic acid pendant arms with a propionate side chain (H5do3apPrA) was proposed on the basis of TRLIFS measurements. The experimental data of the dissociation kinetics of the europium(III) complexes with H5do3ap and H5do3apPrA ligands show that there is no change in reactivity of the complexes due to the side chain of the phosphinic acid bifunctional chelate. The TRLIFS study of the proton-assisted decomplexation reaction of the europium(III) complexes with H3do3a, H4dota, H5do3ap and H5do3apPrA demonstrates different behaviour influenced by a change in the number of water molecules during the reaction. The advantages and disadvantages of the TRLIFS methodology as a new experimental technique for simultaneous evaluation of kinetics and reaction mechanisms are discussed.

Two-photon spectroscopy of europium (III) elpasolites

We present polarized two-photon excitation (TPE) spectra, including Zeeman data, for europium(III) in the elpasolites Cs2NaEuCl6 and Cs2NaYF6:Eu3+. Approximately 80 and 60 levels of unambiguous symmetry have been assigned respectively in each compound up to 32000 cm-1 with the aid of a one-electron crystal field Hamiltonian. This represents the most complete and extensive data set so far reported for Eu(III) at a cubic site. Comparisons are made between comparable data sets for Eu(III) f6 and Tb(III) f8. Deviations from the predictions of the one-electron crystal field model are discussed in terms of the spin correlation crystal field.

Synthesis, characterization, and luminescence properties of the ternary europium complex covalently bonded to mesoporous SBA-15

A novel mesoporous SBA-15 type of hybrid material (phen-SBA-15) covalently bonded with 1, 10-phenanthroline (phen) ligand was synthesized by co-condensation of tetraethoxysilane (TEOS) and the chelate ligand 5-[N,N-bis-3-(triethoxysilyl)propyl]ureyl-1,10-phenanthroline (phen-Si) in the presence of Pluronic P123 surfactant as a template. The preservation of the chelate ligand structure during the hydrothermal synthesis and the surfactant extraction process was confirmed by Fourier transform infrared (FTIR) and 29Si MAS NMR spectroscopies. SBA-15 consisting of the highly luminescent ternary complex Eu(TTA)3phen (TTA = 2-thenoyltrifluoroacetone) covalently bonded to a silica-based network, which was designated as Eu-(TTA)3phen-SBA-15, was obtained by introducing the Eu(TTA) 3?·2H2O complex into the hybrid materials via a ligand exchange reaction. XRD, TEM, and N2 adsorption measurements were employed to characterize the mesostructure of Eu(TTA)3phen-SBA- 15. For comparison, SBA-15 doped with Eu(TTA)3?·2H2O and Eu(TTA)3phen complexes and SBA-15 covalently bonded with a binary europium complex with phen ligand were also synthesized, and were named SBA-15/Eu(TTA)3, SBA-15/Eu(TTA)3phen, and Eu-phen-SBA-15, respectively. The detailed luminescence studies on all the materials showed that, compared with the doping sample SBA-15/Eu(TTA)3phen and binary europium complex functionalized sample Eu-phen-SBA-15, the Eu(TTA) 3phen-SBA-15 mesoporous hybrid material exhibited higher luminescence intensity and emission quantum efficiency. Thermogravimetric analysis on Eu(TTA)3phen-SBA-15 demonstrated that the thermal stability of the lanthanide complex was evidently improved as it was covalently bonded to the mesoporous SBA-15 matrix. ? 2005 American Chemical Society.

From structural properties of the EuIII complex with ethylenediaminetetra(methylenephosphonic acid) (H8EDTMP) towards biomedical applications

Crystals of EuIII with ethylenediaminetetra(methylenephosphonic acid) (H8EDTMP) and with ethylenediaminetetraacetic acid (H 4EDTA) have been synthesized in the same experimental conditions and their X-ray analyses have been performed. The EDTMP ligand wraps the Eu III ion in a fashion similar to its carboxylic analogue, EDTA, i.e. coordinating through two nitrogen atoms and four oxygen atoms in such a way that only one oxygen atom from each phosphonate group is bonded to the central ion. The coordination sphere is completed by two oxygen atoms of the bidentate carbonate anion in the case of the EuIII-EDTMP complex, whereas the inner sphere of the EuIII-EDTA crystal is completed by three water molecules. Spectroscopic studies (UV-Vis and 31P NMR spectra) of EuIII-EDTMP solutions at controlled pH showed that the replacement of inner sphere water molecules and/or OH hydroxy groups by a carbonate anion in the EuIII-EDTMP complex at physiological pH results in the formation of [Eu(EDTMP)(CO3)]7- species which is thermodynamically stable and kinetically inert. The affinity of the carbonate anion towards the EuIII-EDTMP species was studied by analysis of f-f intensities and luminescence decay rates. The dissociation constant of the Eu III-EDTMP-carbonate complex was found to be approximately 43 mM. The presented results may be helpful in understanding the role played by the 153SmIII-EDTMP complex known as Quadramet in the seeking of metastatic tissue in bones as well as possibly giving some premises for future ligand design of these types of complexes with lanthanide radionuclides.
