Crystal and molecular structures of the adducts (Cp2YCl)2.L (L = 2THF, DME, 1,4-.dioxane)

Abstract

The yttrium(III) adducts, (Cp2YCl)2. C4H8O (5), [(Cp2YCl)2. C4H8O2]n (6) and Cp2Y(C4H10O2)(m-Cl)(Cl)YCp2 (7) were prepared by reactions of (Cp2YCl)2 with corresponding O-bases and were characterized by X-ray crystallography. The complex 5 consists of (Cp2YCl)2 dimers bonded with two THF molecules (dY-O = 2.478E). In adduct 6 the (Cp2YCl)2 dimers are linked by 1,4-dioxane into a polymeric chain with long (dY-O = 2.601 E) bonds. In the asymmetric adduct 7 the DME molecule is bonded with one Y atom by both oxygen atoms (dY-O = 2.382, 2.448 E) and the single bridge Y-Cl-Y bond is only presented.
