three-coordinate zinc methyl 2b–d and zinc ethyl 3b–d. The bis-ligand complexes 4a,b,d were isolated by either protonolysis of alkyls 2–3 with one equivalent of H[1] or metathesis of ZnX2 (X = Cl, OAc) with the corresponding lithium derivatives 5. Attempts to prepare [1a–d]ZnX (X = Cl, OAc) were not successful regardless of stoichiometry of the starting materials employed. Alcoholysis of zinc alkyls 2–3
