摘要：

(Butadiene)zirconocene adds 1 molar equiv of aluminum trichloride to give CP2Zr(mu-C4H6)(mu-Cl)AlCl2 (3). Complex 3 crystallizes in space group P2(1)/n with cell parameters a = 9.124 (1) angstrom, b = 15.040 (1) angstrom, c = 11.737 (1) angstrom, beta = 93.60 (1)-degrees, Z = 4, R = 0.024, and R(W) = 0.032. In the crystal the butadiene carbon centers C(1) and C(2) are bonded to zirconium (Zr-C(1) = 2.348 (2) angstrom, Zr-C(2) = 2.525 (3) angstrom), whereas the Zr-C(3) separation is large at 3.04 angstrom. The butadiene C(4)-Al bond length is 1.966 (2) angstrom. A "pi-agostic" interaction may serve to describe the special bonding situation observed in complex 3.
