The
formation of mixed-valent ytterbium and europium complexes
L4LnIII2LnII (Ln = Yb
(1), Eu (2)) was observed for the first
time in the spontaneous reduction reaction system of quinolinyl aminophenol
(H2L) with Ln[N(SiMe3)2]3 (Ln = Yb, Eu) in toluene at 90 °C, whereas the same reaction
with Sm[N(SiMe3)2]3 gave the expected
monoamido samarium complex LSmN(SiMe3)2(DME)
(4). The isolation of the binuclear ytterbium complex
L3Yb2 (3) under mild conditions
demonstrates that the transformation from a trivalent ytterbium complex
to the mixed-valent ytterbium species 1 may involve a
ligand redistribution reaction and homolysis of the Yb–N bond.
