静电相互作用是离子液体的特征，在溶质溶解于离子液体中时，静电相互作用对物质的形成起着关键作用。研究了某些ILs的新物种/配合物的形成。然而，这些研究还没有集中在共晶液体上，而共晶液体是一种很有前途的液体。这些液体（或液体配位配合物，LCCs）是相当新的，由金属的阳离子和阴离子氯配合物组成。迄今为止，这些液体已被用作沉积金属的电解质和催化的溶剂。本研究处理了一种液体，该液体由AlCl3和1-丁基吡咯烷的摩尔比为1.2:1混合而成。用光谱学方法研究了FeCl2与有机分子的相互作用。发现溶解的Fe（II）主要与IL阴离子相互作用，这种相互作用会导致电解质阳离子的变化。此外，还探讨了制备Fe和Fe- al厚磁膜的可行性。
Electrostatic interactions are characteristic of ionic liquids (ILs) and play a pivotal role in determining the formation of species when solutes are dissolved in them. The formation of new species/complexes has been investigated for certain ILs. However, such investigations have not yet focused on eutectic liquids, which are a promising class of ILs. These liquids (or liquid coordination complexes, LCCs) are rather new and are composed of cationic and anionic chloro complexes of metals. To date, these liquids have been employed as electrolytes to deposit metals and as solvents for catalysis. The present study deals with a liquid that is prepared by mixing a 1.2:1 mol ratio of AlCl3 and 1-butylpyrrolidine. An attempt has been made to understand the interactions of FeCl2 with the organic molecule using spectroscopy. It was found that dissolved Fe(II) species interact mainly with the IL anion and such interactions can lead to changes in the cation of the electrolyte. Furthermore, the viability of depositing thick magnetic films of Fe and Fe-Al has been explored.
