  摘要：

  A new class of Zr-M heterobimetallic complexes (M = Fe, Ru, Co) containing the {CH2(CH(2)NSiMe(3))(2)(Cp)Zr} fragment as a building block has been synthesized by salt metathesis of CH2(CH(2)NSiMe(3))(2)(Cp)ZrCl (5) with K[CpM'(CO)(2)] (M' = Fe, Ru) and Na[Co(CO)(3)(PR(3))] (R = Ph, Tol). The zirconium half-sandwich complex 5 was obtained in four reaction steps from ZrCl4 via the spirocyclic complex [CH2(CH(2)NSiMe(3))(2)]Zr-2 (1), the (diamido)dichlorozirconium complex CH2(CH(2)NSiMe(3))(2)ZrCl2 (2), and its soluble THF-adduct CH2(CH(2)NSiMe(3))(2)ZrCl2(THF)(2) (3). The latter was converted to 5 in good yield by reaction with LiCp. The Zr-Fe heterodinuclear complex CH2(CH(2)NSiMe(3))(2)(Cp)Zr-Fe(CO)(2)Cp (6) has been characterized by X-ray crystal structure analysis which has established the presence of an unsupported Zr-Fe bond. The nu(CO) infrared bands of the CpM'(CO)(2) moieties in the Zr-M' complexes (M' = Fe, Ru) indicate a significant ionic contribution to the Zr-M' bonding.

  The synthesis, structural, and theoretical characterization of heterobimetallic complexes CH3Si-SiMe2N(4-CH3C6H4)}3M-Co(CO)3(L) (M = Ti, Zr; L = CO, PPh3, PTol3) with unsupported metal-metal bonds between cobalt atoms and titanium or zirconium atoms is being reported. The synthesis of the dinuclear compounds was achieved by salt metathesis of the chlorotitanium and zirconium complexes and the alkalimetal
