The crystal and molecular structure of dinitrato(1,7,10,16‐tetraoxa‐4,13‐diazacyclooctadecane)europium(III) nitrate, ([Eu(NO3)2(C12H26N2O4)]NO3) has been determined from single‐crystal X‐ ray diffraction: a = 12.567(3), b = 11.585(3), c = 16.354(5) Å, β = ...
The photophysical properties of the triple-stranded dimetallic helicates [Ln2(LC−2H)3]·H2O (Ln = Nd, Sm, Dy, Yb) are determined in water and D2O solutions, and energy transfer processes are modeled for SmIII. The luminescence of NdIII, SmIII, and YbIII is ...
The ionic liquid 1-dodecyl-3-methylimidazole chloride ([C12- mim]Cl) is doped with 1 mol-% of the lanthanide ternary complexes [Ln(tta)3(phen)] (tta = thenoyltrifluoroacetonate, phen = 1,10-phenanthroline, Ln = Nd, Eu, Er, Yb), resulting in luminescent mes ...
A series of new mixed-ligand lanthanide complexes [Ln(hfa)3(4-cpyNO)]2 (Ln = SmIII-HoIII and TmIII; hfa- = hexafluoroacetylacetonate; 4-cpyNO = 4-cyanopyridine N-oxide) have been synthesised by treating the corresponding lanthanide hexafluoroacetylacetonat ...
The isolation and characterization of Ln(NO3)3 complexes (Ln=La, Pr, Nd, Eu, Tb, Lu) with 2,3-benzo-1,4,7,13-tetraoxa-10-azacyclo-penta-decane (L1) and two of its N-substituted derivatives (L2, L3) are reported. Structural information in the solid state is ...
The invention provides a novel podate ligand H4L[1,2,4,5-tetrakis(pyrazol-1-ylmethyl-3-carboxylic acid)benzene] and to complexes comprising the ligand and a metal ion. Pharmaceutical compositions and methods of making and using the metal-podate complex ...
Due to their high and variable coordination numbers leading to poorly predictable threedimensional coordination spheres, the trivalent lanthanide metal ions are challenging molecular objects for introduction into thermotropic liquid crystals. Conversely, t ...
Clusters containing nine lanthanide and six sodium ions are crystallized with the help of a tridentate ligand bearing a phosphonic acid group; the structure of the EuIII compound reveals a host-guest assembly Eu⊂Na6Eu8L16 with a substantial quantum yield ( ...
