Synthesis and Structural Characterization of New Zinc Amidinate Complexes

The synthesis and reactivity of heteroleptic zinc complexes of the type LZnX (X = Me, I) containing amidinate ligands L of varying steric bulk were investigated. Complexes of the type LZnMe, which were obtained from the homoleptic complexes L2Zn upon reaction with ZnMe2, react with iodine with subsequent formation of LZnI. Single-crystal X-ray structures of the amidinate zinc complexes [{MeC(Ni-Pr)2}ZnMe]2, 1, [{MeC(Ni-Pr)2}ZnI]2LiI(OEt)2, 3, [t-BuC(NDipp)2]ZnMe, 5, [t-BuC(NDipp)2]ZnMe(t-BuPy), 6, [{t-BuC(NDipp)2}Zn(μ-I)]2, 7, and [t-BuC{N(H)Dipp}2][Al{OC(CF3)3}4], 8, are reported.
