摘要:
Novel half-sandwich complexes of the type CpSn(OBu(t))(3)M (M = Ge-II, Sn-II, Pb-II; Cp = C5H5) have been prepared conveniently by salt elimination reactions of CpSnCl with potassium alkoxometalates, [KM(OBu(t))(3)](n). The single-crystal X-ray crystallographic analysis performed on (C5H5)Sn(mu(2)-OBu(t))(2)Ge(OBu(t)) reveals an average effect of eta(3) and eta(1) bonding modes of the cyclopentadienyl ring to the tin atom.
