The reaction of ZnEt2 and i-PrN=C=Ni-Pr in toluene at elevated temperature yields the zinc amidinate complex [{EtC(Ni-Pr)2}ZnEt]2 1. In contrast, the reaction of stronger Lewis acidic MeZnCl with t-BuN=C=Nt-Bu resulted in the formation of the Lewis acid-base adduct Me(Cl)Zn-N(t-Bu)CNt-Bu 2, which adopts a dimeric, Cl-bridged structure in the solid state. 1 and 2 were characterized by elemental analyses, mass and multinuclear (1H, 13C{1H}) NMR spectroscopy (1H, 13C), and single crystal X-ray analysis.
