The complexes of light lanthanides (La-Eu) with 2,6-dihydroxybenzoic acid have been prepared and their IR spectra and thermal decomposition have been investigated. The complexes Ln(C7H5O4)3 x nH2O, where n=4 for La-Sm and n=6 for Eu, when heated lose the crystallization water molecules in one (La-Pr), two (Nd, Sm) or three (Eu) steps and then anhydrous compounds decompose to Ln2O3, CeO2 and Pr6O11 with intermediate formation of instable Ln(C7H5O4)(C7H4O4), except of lanthanum complees, which forms additionally La2O2CO3.
