Nature of the Magnetic Interaction in the (Cu2+, Ln3+) Pairs: An Empirical Approach Based on the Comparison Between Homologous (Cu2+, Ln3+) and (NiLS2+, Ln3+) Complexes

TL;DR: The magnetic interaction in a series of isomorphous Cu2+−Ln3+complexes (1) is antiferromagnetic for LnCe, Nd, Sm, Tm, Yb, while no interaction is operative for ln=La, Pr, Eu, Lu as mentioned in this paper.
Journal ArticleDOI

Experimental Evidence of a Ferromagnetic Ground State (S = 9/2) for a Dinuclear Gd(III)−Ni(II) Complex

TL;DR: In this paper, the structural determination of a dinuclear Gd(III)−Ni(II) entity confirms the strict dinuclearity of the complex while the magnetic properties evidence the presence of a ferromagnetic interaction between the paramagnetic (S = 1) nickel ion and the gadolinium center.
Journal ArticleDOI

Homo- (4f, 4f) and Heterodimetallic (4f, 4f') Complexes. The First Structurally Characterized Example of a Heterodimetallic (Yb, La) Complex (1'). Magnetic Properties of 1' and of a Homodinuclear (Gd, Gd) Analogue.

TL;DR: A structural determination confirms that the tripodal ligand tris[4-(2-hydroxy- 3-methoxyphenyl)-3-aza-3-butenyl]amine (LH3) offers two coordination sites, an inner N4O3 one and an outer O6 one, thus providing access to a general route for the preparation of homo- and heterodinuclear complexes.
Journal ArticleDOI

The non-template synthesis of novel non-symmetrical, tetradentate Schiff bases. Their nickel(II) and cobalt(III) complexes

TL;DR: In this paper, a non-symmetrical, tetradentate Schiff base has been obtained in a two-step process, in which one mole of ethylene diamine is reacted with one Mole of acetylacetone to afford a 1:1 condensation product, which is then reacted with Mole of either salicylaldehyde or 2-hydroxyacetophenone to yield nonsymmetric diimines.
