CRYSTAL AND MOLECULAR STRUCTURES OF THE ADDUCTS
(Cp2YCl)2.L (L = 2THF, DME, 1,4-.DIOXANE)
A.I. Sizov, T.M. Zvukova, Z.A. Starikova, B.M. Bulychev
(Division of Chemical Technology and New Materials)
The yttrium(III) adducts, (Cp2YCl)2. C4H8O (5), [(Cp2YCl)2. C4H8O2]n (6) and Cp2Y(C4H10O2)(μ
μCl)(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 = 2.478 Å). In adduct 6 the (Cp2YCl)2 dimers are linked by 1,4-dioxane
into a polymeric chain with long (dY-O = 2.601 Å) 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 Å) and the single
bridge Y-Cl-Y bond is only presented.
