与已报道的基于芳基羧酸锌的烷基羧酸锌不同，二乙基锌与一系列双(烷基羧酸锌)S锌反应生成了配体化学计量比为3：2的羧酸乙酯配合物。包括单晶X射线衍射在内的分析数据表明，对于“乙酸锌”，产物是一种不寻常的五聚络合物[Zn-5(OAc)(6)(Et)(4)]。
In contrast to previously reported alkylzinc carboxylates based on aryl carboxylates, the reaction between diethylzinc and a series of zinc bis(alkyl carboxylate)s yields complexes with a ligand stoichiometry of carboxylate to ethyl of 3:2. The analytical data, including single-crystal X-ray diffraction., indicate that, for "ethylzinc acetate", the product is an unusual pentameric complex of the form [Zn-5(OAc)(6)(Et)(4)].
