Based on structural evidence and a theoretical analysis, we report here the existence of close contacts between In(III) centres in the crystals of Lewis acid–base adducts that show features of metallophilic interactions and are not present for the lighter elements of group 13.

In（iii）⋯In（iii）短接触：未注意到的嗜金属相互作用？†

基于结构证据和理论分析，我们在此报告路易斯酸碱加成物晶体中In（III）中心之间存在紧密接触，该接触显示出亲金属相互作用的特征，而对于第13组轻元素而言则不存在。
