摘要：

The reaction of (C5HMe4)2TiCl2 with Mg in THF in the presence of Me3SiC=CC=CSiMe3 afforded the bimetallic Ti(III)-Mg tweezer complex [(eta5-C5HMe4)2Ti(eta1-C=CSiMe3)2][Mg(THF)Cl] (1). Complex 1 crystallizes in the monoclinic space group P2(1)/c with a = 19.510(6) angstrom, b = 10.103(4) angstrom, c = 19.817(7)angstrom, beta = 112.50(2)degrees, Z = 4, and V = 3608.6 angstrom3. The Mg atom is embedded between the C=C bonds in a pi-bonding position at an average Mg-C distance of 2.275 angstrom to the inner and 2.463 angstrom to the outer carbon atoms.
