Effect of reaction temperature on the chlorination of a Sm 2O3-CeO2-C mixture

The chlorination of a Sm2O3-CeO2-C mixture with gaseous chlorine was studied by thermogravimetry (TG). The effect of the reaction temperature between 400 and 950°C on the reaction rate was analyzed. The reaction products were studied by X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). Compared to the results previously found in the individual systems, it was concluded that each oxide evolves as being an individual in the mixture. Combined with TG results along with observations done using scanning electron microscopy (SEM), the stoichiometries of the reactions involved were obtained. From these results, a two-stage separation method for both oxides was proposed.

SYNTHESIS AND STRUCTURAL STUDY OF SAMARIUM HEXACYANOFERRATE (III) TETRAHYDRATE, SmFe(CN)6 multiplied by (times) 4H2O.

Single crystals of SmFe(CN)//6 multiplied by (times) 4H//2O prepared from an aqueous solution under ambient conditions have been used for single-crystal diffraction, thermal gravimetric analysis, and infrared spectrometric studies. This characterized compound is compared to previously reported LnT(CN)//6 (T equals Cr, Fe, Co) structures. Samarium hexacyanoferrate (III) tetrahydrate is found to be monoclinic, not hexagonal or orthorhombic as presupposed. SmFe(CN)//6 multiplied by (times) 4H//2O crystallizes in space group P2//1/m (No. 11), a equals 7. 431(1), b equals 13. 724(3), c equals 7. 429(2) Angstrom, beta equals 119. 95(1) degree , Z equals 2. Full-matrix least-squares refinement has yielded the final values of R equals 0. 0292 and R//w equals 0. 0296 for 1028 unique reflections. The observed and calculated densities are 2. 198(3) and 2. 197 Mg m** minus **3, respectively.

The first dinitrile frameworks of the rare earth elements: ∞3[LnCl3(1,4-Ph(CN)2)] and ∞3[Ln2Cl6(1,4-Ph(CN) 2)], Ln = Sm, Gd, Tb, Y; access to novel metal-organic frameworks by solvent free synthesis in molten 1,4-benzodinitrile

The three-dimensional frameworks ∞3[LnCl 3(1,4-Ph(CN)2)] of the lanthanides Ln = Sm (1), Gd (2), Tb (3), and ∞3[Ln2Cl6(1,4-Ph(CN) 2)] for the group 3 metal Y (4) were obtained as single crystalline materials by the reaction of the anhydrous chlorides of the referring rare earth elements with a melt of 1,4-benzodinitrile. No additional solvents were used for the reactions. The dinitrile ligand is strongly coordinating and substitutes parts of the chlorine coordination. The Ln halide structures are reduced to two-dimensional networks, whereas coordination of both nitrile functions to the metal ions renders bridging in the third direction accessible. This enables formation of new metal organic framework (MOF) structure types with the large 1,4-benzodinitrile spacers interlinking ∞2[LnCl 3] planes. In comparison to 1,4-Ph(CN)2 the mono functional benzonitrile ligand does not constitute framework structures, which is underlined by comparison with a reaction of yttrium chloride with PhCN resulting in the molecular complex [Y2Cl6(PhCN) 6] (5) with end-on coordination PhCN ligands. The coordination spheres of the rare earth ions consist of double capped (∞ 3[LnCl3(1,4-Ph(CN)2)] (1-3)) as well as single capped trigonal prisms (∞3[Ln2Cl 6(1,4-Ph(CN)2)] (4)) of chloride ions and N≡C groups while 5 displays edge sharing pentagonal bipyramids as coordination polyhedra. Sm (1), Gd (2), and Tb (3) exhibit isotypic framework structures with intercrossing dinitrile ligands. The group 3 metal Y (4) gives a framework with a coplanar arrangement of ligands and a lower ligand content. The largest cavities within the MOF structures of 1-4 have diameters of 3.9-8.0 A. All compounds were identified by single crystal X-ray analysis. Mid IR, Far IR, and Raman spectroscopy, microanalyses and simultaneous Differential Thermal Analysis-Thermogravimetry (DTA/TG) were also carried out to characterize the products.

Synthesis of 2,6-dialkoxylphenyllanthanoid complexes and their polymerization catalysis

The 1:1-2:1 reaction of [2,6-(iPrO)2C6H3]Li with anhydrous SmCl3 in THF gave [2,6-(iPrO)2C6H3]3 Sm 1 exclusively, while the 3:1 reaction gave [2,6-(iPrO)2C6H3]4SmLi 2 as major product, which crystallizes in the monoclinic space group C2/c(No. 15) with a=47.52(1) A, b=11.680(9) A, c=18.862(9) A, β=112.19(3)°, V=9694(8) A3, Z=8, R=0.077 and Rw=0.074. In a similar manner, [2,6-(iPrO)2C6H3]3La was obtained by reacting with LaCl3(THF)2. The 2:1 reaction of [2,6-(iPrO)2C6H3]Li with YbCl3 gave [2,6-(iPrO)2C6H3]2YbCl, which produces [2,6-(iPrO)2C6H3] 2Yb[CH(SiMe3)2]2Li 4 by reaction with (SiMe3)2CHLi. Polymerizations of ε-caprolactone and alkyl isocyanates were examined using the resulting complexes.

Raman spectroscopic study of molten SmCl3-ACl systems (A=Li, Na, K)

Raman spectra of molten SmCl3-ACl systems (A = Li, Na, K) were measured at different compositions and temperatures. The spectra showed polarized peaks centered at about 256 cm-1 in the whole range of concentration and depolarized peaks at about 120 cm-1 in the low concentration range of SmCl3. These Raman shifts were identified as the totally symmetric stretching vibration v1 and the degenerate bending vibration v5 of octahedral SmCl63- complex anion, respectively. Peak splitting of the isotropic component was recognized clearly in the reduced Raman spectra of mixtures. Clustering of complex anions is thought to occur in the melts. However, the clustering might be restrained when the SmCl3 concentration became relatively low by adding LiCl, NaCl or KCl. The v5 peak was the strongest at the SmCl3 concentration of 25 mol% in the SmCl3-KCl system among the three systems. The temperature effect on the Raman shift, reflecting the structural change, was negligibly small between 823 K and 1023 K.

Synthesis, thermal properties and spectroscopic study of solid mandelate of light trivalent lanthanides

Characterization, thermal stability and thermal decomposition of light trivalent lanthanide mandelates Ln(C6H5CH(OH)CO 2)3·nH2O (Ln = La to Gd, except Pm) were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), differential scanning calorimetry (DSC), experimental and theoretical infrared spectroscopy, elemental analysis, X-ray diffractometry, complexometry and TG-DSC coupled to FTIR. The dehydration of the lanthanum, samarium, europium and gadolinium compounds occurs in a single step while for praseodymium and neodymium ones it occurs in two consecutive steps. The thermal decomposition of the anhydrous compounds occurs in three, four or five consecutive steps, with formation of the respective oxides CeO2, Pr6O11 and Ln2O3 (Ln = La, Nd to Gd) as final residues. The results also provide information concerning the composition, thermal behavior and gaseous products evolved during the thermal decomposition of these compounds. The theoretical and experimental spectroscopic data suggest the possible modes of coordination of the ligand with the lanthanum.

Preparation and characterization of rare earth orthoborates, LnBO 3 (Ln = Tb, La, Pr, Nd, Sm, Eu, Gd, Dy, Y) and LaBO3:Gd, Tb, Eu by metathesis reaction: ESR of LaBO3:Gd and luminescence of LaBO3:Tb, Eu

Lanthanide orthoborates of composition LnBO3 (Ln = Tb, La, Pr, Nd, Sm, Eu, Gd, Dy, Y) and LaBO3:Gd, Tb, Eu have been prepared by metathesis reaction. This method provides a convenient route for the synthesis of orthoborates and its solid solutions at low temperatures. Powder X-ray diffraction and FT-IR spectroscopy were used to characterize these borates. Rare earth borates, (LnBO3) are isomorphous with different forms of CaCO3 depending on the radius of rare earth ion. LaBO3, LaBO3:Gd, Tb, Eu, PrBO3, NdBO3 crystallized in aragonite structure, SmBO3 crystallized in H-form and TbBO 3, EuBO3, GdBO3, DyBO3, YBO 3 crystallized in vaterite structure. The structural analysis of TbBO3 was carried out. The morphology of these borates was obtained from Scanning electron microscopy. Spin-Hamiltonian parameters for Gd 3+ are deduced from room temperature electron spin resonance spectrum of LaBO3:Gd. The luminescence of LaBO3:Tb, Eu gave characteristics peaks corresponding to Tb3+, Eu3+ respectively.
