摘要：

Cp(2)TiX(2)-(i)PrMgX(Cp' = C(5)HMe(4), C(5)H(2)Me(3), C5H5; X = Cl or Br) systems afford blue crystalline products, with low solubility in diethyl ether. X-Ray single crystal analysis of the C(5)HMe(4) derivatives revealed dimeric centrosymmetric structures of [(C(5)HMe(4))(2)Ti(mu-H)(2)Mg(OEt(2))(mu-Cl)](2) (Ia) and [(C(5)HMe(4))(2)Ti(mu-H)(2)Mg(OEt(2))(mu-Br)](2) (Ib). The solution EPR spectra of all the compounds (g = 1.9910-1.9934, a(H) = 0.66-0.75 mT, a(T)i = 0.54-0.66 mT, a(multiplet) = 0.04-0.1 mT) can be assigned either to the dimers or to the dissociated monomeric species.
