The reaction of ytterbium metal, HgPh 2 and N ‐(2‐methoxyphenyl)‐ N ‐(trimethylsilyl)amine (L 1 H) or N ‐(2‐phenoxyphenyl)‐ N ‐(trimethylsilyl)amine (L 2 H) in tetrahydrofuran (thf) unexpectedly yielded the ytterbium(III) complexes [Yb(L 1 ) 2 (μ‐OMe)] 2 (1) and [Yb(L 2 ) 2 (OPh)(thf)] (2) , the structures of which were established by X‐ray crystallography. These are considered to be derived from C−O bond cleavage of the ligand aryl ether moiety by an initially formed Yb II species, e.g. the thermally unstable, but crystallographically authenticated [Yb(L 1 ) 2 (thf) 2 ] (3) , which was independently prepared from [Yb{N(SiMe 3 ) 2 } 2 (thf) 2 ] and L 1 H.
