Abstract

The germanium hydroxide complexes LGe(mu-O)M(THF)Cp2 (M = Yb, 1; Y, 2; L = HC[C(Me)N(Ar)]2; Ar = 2,6-iPr2C6H3) were prepared by the reaction of LGeOH with Cp3M (M = Yb, Y) in THF at ambient temperature with the elimination of HCp. 1 and 2 are pale-yellow solids. Both compounds crystallize isotypically as monomers in a triclinic space group P (pseudo-merohedrally twinned, two independent molecules) and were found to be stable in the solid state and in solution at room temperature. The six-membered C3N2Ge rings in 1 and 2 display a boat conformation with the germanium and the gamma-C out-of-plane. The Ge-O-M skeleton exhibits a bent arrangement (angles 151-154 degrees ). The 1H NMR investigation of 2 confirmed that the solid-state structure is also found in solution.
