摘要：

The complexes of 2,3,4-trimethoxybenzoic acid with Tb(III), Dv(III), Hod(III), Er(III), Trn(III), Yb(III), Lu(III) and Y(III) are Crystalline, anhydrous salts with colours typical of the M(111) ions, The carboxylate group is probably a bidenate. chelatin ligand, The thermal stabilities of the complexes were examined under an air atmosphere in the temperature range 293-1273 K. The solubility in water at 293 K for all the heavy lanthanide(III) andyttrium(III) complexes are in the order of 10(-3) mol dm(-3). The magnetic moments of the complexes were determined in the temperature range 77-300 K.
