摘要：

A series of lanthanide(III) complexes constructed from Schiff base and beta-diketonate ligands have been synthesized by the same method. They are mononuclear complex [Ln(hfac)(3)(L)] (Ln = Nd (1), Sm (2), Eu (3)), tetranuclear complex [Gd-4(OAc)(2)(hfac)(10)(L)(3)] (4), dinuclear-mononuclear cocrystal {[Dy(hfac)(2)(L)](2)(OAc)}center dot[Dy(hfac)(4)] (5), and mononuclear-mononuclear cocrystal [Yb(hfac)(2)(L)]center dot[Yb(hfac)(4)] (6) (L = N,N'-bis(pyridine)-1,2-ethanediamine, hfac = hexafluoroacetylacetonate). Complexes 1-3 and 6 exhibit characteristic metal-centred emission not only in the solid state but also in solution. Lifetimes and quantum yields of luminescence are also determined.
