  N,N′-Ethylene-bis(3-methoxysalicylideneimine) mononuclear (4f) and heterodinuclear (3d–4f) metal complexes: Synthesis, crystal structure and luminescent properties

  摘要：

  The stepwise synthesis of mononuclear (4f) and heterodinuclear (3d-4f) Salen-like complexes has been investigated through structural determination of the intermediate and final products occurring in the process. In the first step, reactions of ligand H2L and Ln(NO3)(3)center dot 6H(2)O give rise to three mononuclear lanthanide complexes Ln(H2L)(NO3)(3) [H2L = N,N'-ethylene-bis(3-methoxysalicylideneimine), Ln = Nd (1), Eu (2) and Tb (3)], in which N,N'-ethylene-bis(3-methoxysalicylideneimine) acts as tetradentate ligands with the O2O2 set of donor atoms capable of effective coordination. These species are fairly stable and have been isolated. Then, addition of Cu(Ac)(2)center dot H2O to the mononuclear lanthanide complex yields expected heterodinuclear (3d-4f) complexes Cu(L)Ln(NO3)(3)center dot H2O [Ln = Nd (4) and Eu (5)] where the Cu(II) ion is inserted to the inner N2O2 cavity. Luminescent analysis reveals that complex 3 exhibits characteristic metal-centered fluorescence of Tb(III) ion. However, the characteristic luminescence of both Sm(III) and Eu(III) ions is not observed both in solution and solid state of the complexes. (C) 2007 Elsevier B.V. All rights reserved.
