Abstract:
We report the synthesis and characterization of ionic compounds [(thf)4YbI]2[Ge9(Hyp)3]2 (1) and [(thf)5LnI]4[Ge9(Hyp)3]4 (Ln = Eu (2), Sm (3)), (Hyp = Si(SiMe3)3). All compounds were examined by UV-Vis spectroscopy and a blue luminescence of Eu2+ was found. The solid state magnetic measurements of complexes 2 and 3 confirmed the presence of divalent lanthanides.
