| Abstract/Summary |
The complexes of rare earth elements with 2,3-dimethoxybenzoic acid of the formula Ln(C9H9O4)3 · nH2O, where Ln = La(III), Ce(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III), Ho(III), Er(III), Tm(III), Yb(III), Lu(III), and Y(III), and n = 2 for Tb, Dy, Ho, Y, n = 1 for Er, Tm, n = 0 for La, Gd, Yb, and Lu have been synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric studies, as well as by X-ray and magnetic measurements. The complexes have colours typical for Ln3+ ions. The carboxylate group is a bidentate, chelating ligand or tridentate chelating and bridging one. The complexes are crystalline compounds characterized by low symmetry. On heating in air to 1173 K they decompose in various ways.
