The structural studies of bis(iodozinciomethane) in solution was examined. It was performed based on the detailed fine structural studies by AXS and on the macroscopic structural studies by SAXS. It was tuned out that bis(iodozincio)methane exists as amonomeric form without aggregation. The combination of AXS and SAXS is reliable and widely applicable method for the structural studies of many types of organometallic compounds in solution.The structure of bis(iodozincio)methane implies the characteristic Lewis acidity, as a carbon accompanies a couple of zinc atoms. Treatment of 1,2-diketones with bis(iodozincio)methane gave cyclopropane- 1,2-diols. Treatment of 2,3-epoxyalcohol with bis(iodozincio)methane cause the pinacol type rearrangement.

对溶液中双(碘锌甲烷)的结构研究进行了检查。它是基于 AXS 的详细精细结构研究和 SAXS 的宏观结构研究而进行的。结果表明，双(碘锌)甲烷以单体形式存在，没有聚集。 AXS 和 SAXS 的结合是溶液中多种有机金属化合物结构研究的可靠且广泛适用的方法。双（碘锌）甲烷的结构意味着特征性的路易斯酸性，因为一个碳伴随着一对锌原子。用双(碘锌)甲烷处理1,2-二酮得到环丙烷-1,2-二醇。用双(碘锌)甲烷处理2,3-环氧醇会导致频哪醇型重排。
