Abstract

Reactions of ZnX₂ (X = Cl, Br) with equimolar amounts of Li[t-BuC(NR)₂] (R = i-Pr, Cy) yielded mono-amidinate complexes [{t-BuC(NR)₂}ZnX]₂ (X = Cl, R = i-Pr 1, Cy 2; X = Br, R = i-Pr 3, Cy 4), whereas reactions with two equivalents of Li-amidinate resulted in the formation of the corresponding bis-amidinate complexes [t-BuC(NR) ₂]₂Zn (R = i-Pr 5, Cy 6). 1 - 6 were characterized by elemental analyses, IR, mass and multinuclear NMR spectroscopy (¹H, ¹³C), and single crystal X-ray analysis (1, 2, 3, 6). In addition, the single crystal X-ray structure of [t-BuC(NCy)₂] ZnBr·LiBr(OEt₂)₂ 7, which was obtained as a byproduct in low yield from re-crystallization experiments of 4 in Et ₂O, is reported.
