Abstract
A new divalent ytterbium complex, [{(L^Ph^)Yb^II^(Et~2~O)(thf)}~2~(μ‐KI)] {L^Ph^ = Ph~2~Si(NAr)~2~, Ar = 2,6‐__i__Pr~2~C~6~H~3~} (3), was synthesized by the reaction of [(L^Ph^)Yb^III^I(thf)~2~] (2) and an excess of potassium. The bimetallic ytterbium(II) species with bulky diamido ligands are bridged by a KI molecule with cation–π interactions. These two complexes have been fully characterized, particularly by X‐ray crystallography.
