Abstract: A complex of(C6H5)Yb(C9H7)·2THF(Ⅰ) has been synthesized by reacting aGrignard-type reagent C6H5 YbI with K C9H7 in THF.It is a first Yb(Ⅱ) complex containingboth π-ligand(indenyl)and dligand(phenhyl ).The similar reaction carried out in 1,2-dimethoxyethane(DME) gave (C6H5)Yb(C9H7)·DME(Ⅱ).Treatment of(Ⅰ) with diox-ane yielded(C6H5)Yb(C9H7)·THF·(1/2)Dioxane(Ⅲ).The three complexes(Ⅰ),(Ⅱ),and(Ⅲ)were analyzed by elemental analysis,IR,MS and 1H NMR measurements.
