The complexes [Ln(3-SBA)(IP)OH(H2O)]·H2O (Ln = Gd 1 and Eu 2, 3-SBA = 3-sulfobenzoate, and IP = 1H-imidazo[4,5-f][1,10]-phenanthroline) feature 1D chain structure. White-light emission was realized based on the doping concentration of the Eu(III) ion in the Gd(III) complex for the first time. This result opens up a new synthetic strategy for white light emitting materials through two component ...

The geometrical and electronic structures of Ln[(H2O)9]3+ and [Ln(BTP)3]3+, where Ln = Ce-Lu, have been evaluated at the density functional level of theory using three related exchange-correlation (xc-)functionals. The BHLYP xc-functional was found to be most accurate, and this, along with the B3LYP functional, was used as the basis for topological studies of the electron density via the quantu...

Lanthanide(III) complexes [Ln(R-tpy)(cur)(NO3)2] (Ln = La(III) in 1, 2; Gd(III) in 5, 6) and [Ln(R-tpy)(scur)(NO3)2] (Ln = La(III) in 3, 4; Gd(III) in 7, 8), where R-tpy is 4′-phenyl-2,2′:6′,2′′-terpyridine (ph-tpy in 1, 3, 5, 7), 4′-(1-pyrenyl)-2,2′:6′,2′′-terpyridine (py-tpy in 2, 4, 6, 8), Hcur is curcumin (in 1, 2, 5, 6) and Hscur is diglucosylcurcumin (in 3, 4, 7, 8), were prepared and the...

Bipyridyl appended ruthenium alkynyl complexes have been used to prepare a range of binuclear homo-metallic ruthenium and hetero-metallic ruthenium-rhenium complexes. The two metal centers are only weakly coupled, as evinced by IR and UV-vis spectroelectrochemical experiments and supported by quantum chemical calculations. The alkynyl complexes of the type [Ru(C≡Cbpy){Ln}] ({Ln} = {(PPh3)2Cp}, ...

A new type of linear tetranuclear Ln-Ni-Ni-Ln (Ln = Dy 1, Gd 2) complexes have been prepared using multidentate ligand N,N’-bis(3-methoxysalicylidene)-1,3diaminobenzene having two sets of NO and OO’ coordination pockets which can selectively accommodate Ni and Ln ions, respectively. The X-ray structure analysis reveals that the Ni ions are bridged by phenylenediimine groups forming a twelvememb...

Pyridine-containing tridentate binding units react with trivalent lanthanide ions, Ln, to give C3-symmetrical nine-coordinate triple helical complexes in which subtle intramolecular interactions control the final structures. While X-ray crystal structures allow some rationalisation in the solid state, the access to solution structures by paramagnetic NMR is limited by the unpredictable variatio...

The reaction of (S)P[N(CH(3))N=CH-C(6)H(3)-2-OH-3-OCH(3)](3) with a Mn(II) salt followed by a Ln(III) salt (Ln = Eu, Gd and Dy), afforded linear heterometallic complexes [L(2)Mn(2)Ln](+) that showed interesting magnetic properties.

Rare-earth metal tris(borohydrides) [Ln(BH4)3(thf)3] (Ln = Y, La, Nd, Sm) are converted with one equivalent of the Brønsted acid [NEt3H]+[BPh4]- in thf into the monocationic bis(borohydride) complexes [Ln(BH4)2(thf)5]+[BPh4]-. They efficiently initiate the ring-opening polymerisation of epsilon-caprolactone.

Five novel complexes were prepared by reacting 2-((E)-(tert-butylimino)methyl)phenol (HL2) with Ln(NO3)3xH2O (Ln = Gd and Dy ; x 6 5, respectively) LnCl3-6H2O Nd, Dy). The crystal structures of the former two Ln(III) nitrate are isostructural coordination sphere is composed three monodentate HL2 ligands bonded to metal centre through phenolic oxygen atom ions coordinated in a bidentate fashion....

Luminescent pentanuclear tetra-decker Ln(III) complexes [Eu5L4(OH)2(NO3)4(H2O)2].NO3.3H2O , [Nd5L4(OH)2(NO3)5MeOH].3MeOH.2H2O and [Eu5L4(CF3SO3)4(MeO)2(H2O)4].CF3SO3.H2O are formed from Ln(NO3)3.6H2O (Ln = Eu (1), Nd (2)) and Eu(CF3SO3)3, respectively (H2L = N,N'-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine).
