The lanthanide contraction revisited.
A complete, isostructural series of complexes with La-Lu (except Pm) with the ligand TREN-1,2-HOIQO has been synthesized and structurally characterized by means of single-crystal X-ray analysis. All complexes are 1D-polymeric species in the solid state, with the lanthanide being in an eight-coordinate, distorted trigonal-dodecahedral environment with a donor set of eight unique oxygen atoms. Th...
متن کاملSystematic study on the structures of salen type lanthanide complexes tuned by lanthanide contraction and corresponding luminescence.
Two types of N,N'-bis(salicylidene)-1,3-propanediamine (H2L) lanthanide complexes, viz. [Ln(NO3)3(H2L)2]·0.2CH3OH [Ln = La (1), Ce (2) and Pr (3)] and [Ln(NO3)3(H2L)2]2·CH2Cl2·CH3OH [Ln = Nd (4), Sm (5), Eu (6), Gd (7), Tb (8) and Yb (9)], have been isolated by reactions of H2L with Ln(NO3)3·6H2O. X-ray crystallographic and PXRD analysis reveal that 1-3 are isomorphic possessing a novel one-dim...
متن کاملIsotope Effect and Lanthanide Contraction for 3d-4f Cyanide-Bridged Complexes Exhibiting Negative Thermal Expansion
We have prepared some 3d-4f cyanide-bridged Ln(DMF)4(H2O)3Fe(CN)6•H2O complexes (Ln = Ce, Sm, Nd, and Gd; DMF = N,N-dimethylformamide) by substituting isotopes to H-substituted H2O and DMF and O-substituted H2O (and normal Hand O-H2O or H-DMF). We examined their crystal structures exhibiting negative thermal expansion and compared in view of hydrogen bonds and lanthanide contraction. Magnetic p...
متن کاملLanthanide Complexes for Luminescence Imaging Applications
In this article, imaging applications of luminescent complexes and recent advances in the design and photophysical behaviour of near-IR responsive complexes are reviewed. Various properties of the luminescent lanthanide complexes are also discussed in detail.
متن کاملLanthanide(III) Complexes of Oxamic Acid
The preparation, for the first time, of the deprotonated complexes of oxamic acid with Ce(III), Pr(III), Nd(III), Sm(III), Eu(III), Dy(III), Ho(III ) and Yb(III ) is reported. Properties, analytical results, conductometric measurements, magnetic moments and spectral data (IR and diffuse reflectance spectra) are discussed in terms of possible structural types and the nature of the bonding. Oxami...
