A new family of 3d-4f dinuclear complexes derived from a chiral Schiff-base ligand, (R,R)-N,N'-bis(3-methoxysalicylidene)cyclohexane-1,2-diamine (H2L), has been synthesized and structurally characterized, namely, [Cu(L)Ln(NO3)3(H2O)] (Ln = Ce (1) and Nd (2)), [Cu(L)Sm(NO3)3]·2CH3CN (3) and [Cu(L)Ln(NO3)3] (Ln = Eu (4), Gd (5 and 5'), Tb (6 and 6'), Dy (7 and 7'), Ho (8), Er (9) and Yb (10)). Structural determination revealed that these complexes are composed of two diphenoxo-bridged Cu(II)-Ln… CONTINUE READING
