Abstract: | The complexes of yttrium(III) and lanthanides(III) with 2-aminoterephthalic acid form the isostructural series of triclinic compounds with a space group P from La to Lu and they have the general formula of Ln2(C8H5O4N)3·8H2O. On heating in air or inert gas atmosphere they lose all water molecules in the temperature range 50–200°C in one or two steps. The anhydrous compounds are stable from 360 to 435°C and then decompose to oxides. |
