摘要:
Two Salen-type ligands (H(2)L(1), 4,4'-dichloro-2,2'-[(1,3-propylene)dioxybis(nitrilomethylidyne)]diphenol and H(2)L(2), 4,4'-dinitro-2,2'-[ethylenedioxybis(nitrilomethylidyne)]diphenol) and their corresponding complexes ({[CoL(1)(MeOH)](2)(OAc)(2)Co} center dot 2MeOH and [CuL(2)](2)) have been synthesized and characterized by element analyses, (1)H NMR, FT-IR and UV-Vis spectra, TG-DTA and single crystal X-ray crystallography. Crystallographic data suggests the octahedral geometry for Co(II) complex and square-pyramidal geometry for Cu(II) complex. Furthermore, the. fluorescence behavior of Cu(II) complex in DMSO is discussed. (C) 2008 Elsevier B. V. All rights reserved.
