Magnetic relaxation behavior of lanthanide substituted Dawson-type tungstoarsenates

Two new polyoxometalate compounds [(CH3)4N]8[Ln(H2O)8]2[(α2-As2W17O61)Ln(H2O)2]2·nH2O (Ln=Er (1), Dy (2)) have been prepared by the trivacant Dawson-type anion [α-As2W15O56]12- and trivalent rare earth ion and characterized by single-crystal X-ray diffraction, IR spectra, thermogravimetric and electrochemical analyses. The centrosymmetric polyoxoanion, {[(α2-As2W17O61)Ln(H2O)2]2}14-, bounded to each other via Ln3+ connecting to terminal W-O oxygen atoms. Furthermore, the polyoxoanions are linked by [Ln(H2O)8]3+ to form an extensive 3D supramolecular network structure depending on hydrogen bond. The magnetic properties of the two compounds have been studied by measuring their magnetic susceptibilities in the temperature range 2.0-300.0 K, indicating the depopulation of the stark components at low temperature and/or very weak antiferromagnetic interactions between magnetic centers. Low-temperature ac magnetic susceptibility measurements reveal a slow magnetic relaxation behavior for 2.

Synthesis and structural characterization of nonanuclear lanthanide complexes

A series of nonanuclear lanthanide oxo-hydroxo complexes of the general formula [Ln9(μ4-O)2 (μ3-OH)8(μ-BA)8- (BA)8]-[HN(CH2 CH3)3]+· (CH3OH)2(CHCl3) (BA = benzoylacetone; Ln = Sm, 1; Eu, 2; Gd, 3; Dy, 4; Er, 5) were prepared by the reaction of hydrous lanthanide trichlorides with benzoylacetone in the presence of triethylamine in methanol and recrystallized from chloroform/methanol (1:10) at room temperature. These five compounds are isomorphous. Crystal data for 1: cubic, Pn3n; T = 180 K; a = 33.8652(4) A; V = 38838.4(8) A3; Z = 6; Dcalcd = 1.125 g cm-3; R1 = 3.37%.

The core of the anionic cluster comprises two vertex-sharing square-pyramidal [Ln5(μ4-O)(μ3- OH)4]9+ units. The compounds were characterized by elemental analysis, IR, fast atom bombardment mass spectra, thermogravimetry, and differential scanning calorimetry. The thermal analysis indicated that the nonanuclear species were stable up to 150 °C. Luminescence spectra of 2 and magnetic properties of 1-5 were also studied.

catena-Poly[[bis[pentaaqua-erbium(III)]-μ-benzenehexacarboxylato] tetrahydrate]

The title compound is composed of one-dimensional polymeric {[Er2(C12O12)(H2O)10] ·4H2O}n chains containing Er in a slightly distorted antiprismatic eightfold coordination. The benzenehexacarboxylate ion is located about an inversion centre. Water molecules of crystallization, linked by hydrogen bonding to water molecules of the rare earth coordination spheres or the carboxylate groups of the organic ligands, fill the space generated by the packing of the separated chains.

Optical properties of single crystals of heavy lanthanide chlorides

Studies of heavy lanthanide chlorides may provide important information on the degree of Ln3+-ligand bond covalency. Monocrystals of LnCl3·6H2O, where Ln = Dy, Ho and Er, were grown and spectroscopic investigations were pe

Near-infrared luminescence from visible-light-sensitized hybrid materials covalently linked with tris(8-hydroxyquinolinate)-lanthanide [Er(III), Nd(III), and Yb(III)] derivatives

A series of new near-infrared (NIR) luminescent lanthanide-quinolinate derivatives [Ln(Q-Si)3] and xerogels (named as LnQSi-Gel, Ln = Er, Nd, Yb) covalently linked with the Ln(Q-Si)3 by using the 8-hydroxyquinoline-functionalized alkoxysilane (Q-Si) have been synthesized. The obtained xerogel materials LnQSi-Gel are rigid and show homogeneous by field-emission scanning electron microscopy (FE-SEM) images. The Fourier-transform infrared (FT-IR), fluorescence spectra of Ln(Q-Si) 3, and LnQSi-Gel were measured, and the corresponding luminescence decay analyses were recorded. Of importance here is that the excitation spectra of the Ln(Q-Si)3 and LnQSi-Gel extend to the region of visible light (more than 500 nm). Upon ligand-mediated excitation with the visible light, the Ln(Q-Si)3 and LnQSi-Gel show the characteristic NIR-luminescence of the corresponding lanthanide ions through the intramolecular energy transfer from the ligands to the lanthanide ions. The good luminescent performances enable these NIR-luminescent xerogel materials to have possible applications in medical diagnostics, laser systems, and optics, etc.
