N2 - Abstract: New silanediamide complexes of rare-earth elements are synthesized: [{Dy(Me2Si(NMes)2)(THF)2}2(μ-Cl)2] (Dy1), [{Ln(Me2Si(NMes)2)(THF)2}2(μ-BH4)2] (Ln2, Ln = Y, Dy), and [{Ln(Me2Si(NMes)2)(THF)2}2 (μ-SPh)2] (Ln3, Ln = Y, Tb, Dy), Mes = 2,4,6-(CH3)C6H2=mesityl. The compounds are isolated as crystalline phases Dy1, Ln2 (Ln = Y, Dy), Y3·2THF, Tb3·2C7H8, Dy3·2THF, and Dy3·2C7H8 and characterized by single crystal X-ray diffraction. All complexes have a binuclear structure; a silanediamide ligand is chelated to each Ln atom, and Cl–,, or SPh– act as bridges. By photoluminescence spectroscopy of the solutions of Tb and Dy complexes in THF it is shown that (Me2Si(NMes)2)2– is an effective ligand antenna, which sensitizes metal-centered emission of these lanthanides.
