Abstract
The conditions of formation of solid Y(III), La(III), Pr(III), Sm(III), Gd(III), Dy(III), Tm(III) and Lu(III) compounds with 2-amino-4-chlorobenzoic acid were determined. The complexes obtained have the general formula: Ln(C6H3NH2ClCOO)3· H2O. Their solubilities in water at 20°C are of the order of 105 mol dm-3. The IR spectra and X-ray diffractograms were recorded. Upon heating, the compounds undergo dehydration. They then decompose to the corresponding oxides, with intermediate formation of LnOCl for the Pr, Sm and Gd compounds.
