Synthesis, structure and magnetic properties of linear heterobimetallic trinuclear Mn2Ln (Ln = Eu, Gd, Dy) complexes.

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.

Single-Molecule Magnet Behavior and Magnetocaloric Effect in Ferromagnetically Coupled Ln-Ni-Ni-Ln (Ln = Dy and Gd) Linear Complexes†

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...

Pentanuclear [2.2] spirocyclic lanthanide(III) complexes: slow magnetic relaxation of the Dy(III) analogue.

The reaction of LnCl3·6H2O (Ln = Dy(3+), Tb(3+) and Ho(3+)) with the multisite coordinating ligand N'-(2-hydroxy-3-(hydroxymethyl)-5-methylbenzylidene)acetohydrazide (LH3) in the presence of pivalic acid (PivH) leads to the formation of three isostructural homometallic pentanuclear complexes, [Dy5(LH)4(η(1)-Piv)(η(2)-Piv)3(μ2-η(2)η(1)Piv)2(H2O)]·Cl·9·5H2O·5MeOH (1), [Tb5(LH)4(η(1)-Piv)(η(2)-Piv...

Luminescence tuning of imidazole-based lanthanide(III) complexes [Ln = Sm, Eu, Gd, Tb, Dy].

To tune the lanthanide luminescence in related molecular structures, we synthesized and characterized a series of lanthanide complexes with imidazole-based ligands: two tripodal ligands, tris{[2-{(1-methylimidazol-2-yl)methylidene}amino]ethyl}amine (Me(3)L), and tris{[2-{(imidazol-4-yl)methylidene}amino]ethyl}amine (H(3)L), and the dipodal ligand bis{[2-{(imidazol-4-yl)methylidene}amino]ethyl}a...

Structural and magnetic properties of some lanthanide (Ln = Eu(iii), Gd(iii) and Nd(iii)) cyanoacetate polymers: field-induced slow magnetic relaxation in the Gd and Nd substitutions.

The lanthanide(iii) cyanoacetate complexes of the formula {[Ln2(CNCH2COO)6(H2O)4]·2H2O}n, where Ln = Eu (), Gd (), Nd (), have been prepared and characterized by X-ray diffraction analysis. Complexes and are isostructural and differ from the binding scheme of the neodymium compound , structurally described earlier. In all cases, the cyano group of the cyanoacetate ligand is not coordinated to t...
