Some new Schiff bases derivates from 2-furaldehyde and phenylenediamines (L 1–3 ) and their complexes with lanthanum (La), samarium (Sm), gadolinium (Gd) and erbium (Er) have been synthesized. These complexes with general formula [Ln(L 1–3 ) 2 (NO 3 ) 2 ]NO 3 ·nH 2 O (Ln=La, Sm, Gd, Er) were characterized by elemental analysis, UV–Vis, FT-IR...
The capacity of metallic ions to form complexes depends on the electric charge and its mass and on the ligands nature. In this study we followed the coordination capacity of the uranyl ion ( $${\text{UO}}_{\text{2}} ^{{\text{2 + }}} $$ ) with a series of Schiff bases. The Schiff bases have been obtained through the condensation of some salicylic aldehyde derivates with a series of diamines. As...
