Previously the authors investigated the possibility of synthesis of the f-block element mixed complexes with {beta}-diketones and organic unsaturated acids. The mixed-ligand complexes of lanthanides [Ln = Nd(III), Sm(III), Eu(III), Tb(III), Dy(III), Ho(III), and Yb(III)] with acetylacetone (acac) and fumaric or maleic acid (AcidH{sub 2}) were synthesized. The mixed-ligand complexes were prepared by the interaction of REE tris(acetylacetonates) [Ln(acac){sub 3}{center_dot} 3H{sub 2}O] with half as much excess of the organic acid in a solution of diethyl ether. According to the data of elemental analysis and thermogravimetric and spectroscopic investigations, the mixed complexes studied are of composition Ln(acac){sub 2}(AcidH){center_dot}H{sub 2}O.
