Abstract:
Isostructural binuclear complexes [Ln2L2(hfac)6] (Ln = Eu, Tb; hfac– = hexafluoroacetylacetonate ion) are synthesized by the interaction of [Ln(hfac)3(H2O)2] with 3,6-bis(diphenylphosphinyl)pyridazine (L). According to the single-crystal XRD data, two Ln(hfac)3 moieties in the complexes are connected by two O,O´-bidentate-bridging ligands L, and the coordination polyhedron Ln@O8 has the geometry of a triangular dodecahedron. The Eu3+ and Tb3+ complexes exhibit characteristic lanthanide-centered photoluminescence in the solid state at 297 K with luminescence quantum yields of 31% and 2% and excited state lifetimes of 707 and 30 μs, respectively, thus indicating that luminescence sensitization by the ligand environment is more effective for Eu3+ than for Tb3+.
