摘要：

Reaction of the new biguanidine (Pr-i)HN-{NH(Pr-i)}CN(CH2)(2)NC{NH(Pr-i)}N(Pr-i)H (1) with M-(CH2Ph)(4) affords the hydrocarbyl complexes [(PrN)-Pr-i{NH-(Pr-i)}CN(CH2)(2)NC{NH(Pr-i)}(NPr)-Pr-i]M(CH2Ph)(2) ([L-4(Pr)]M-(CH2Ph)(4); M = Ti (2), Zr (3)). Structure determinations of 2 and 3 and the reactivity of 3 with 2,6-dimethylphenyl isocyanide indicate that the linked guanidinate ligand system provides a more open metal coordination sphere than do the unlinked analogues.
