Research on σ-hole interactions that include halogen, chalcogen, pnicogen, and tetrel bonding has been accelerating in recent years. These cousins of the H-bond have many similar properties, including geometric preferences and energetics. Most of the work to date has focused on neutral complexes, with less known about these bonds to anions. This review summarizes the current state of knowledge about the complexes of anions with ligands that engage in these sorts of noncovalent bonds. Of particular interest are comparisons with H-bonds, and how the geometry of the fully coordinated complex varies as the number of surrounding ligands increases. A specific application of these ideas is explored in which these noncovalent bonds can be used to selectively bind certain anions in a multidentate arrangement, where a symbiotic interplay of experimental and computational methods has provided some useful insights.

近年来，对包括卤素，硫属元素，发烟性元素和t特尔键的σ-空穴相互作用的研究一直在加速。H键的这些表亲具有许多相似的属性，包括几何首选项和能量学。迄今为止，大多数工作都集中在中性络合物上，而对这些与阴离子的键所知甚少。这篇综述总结了有关阴离子与参与这类非共价键的配体的配合物的知识的现状。特别令人感兴趣的是与氢键的比较，以及随着周围配体数量的增加，完全配位的配合物的几何形状如何变化。探索了这些想法的特定应用，其中这些非共价键可用于以多齿排列选择性地结合某些阴离子，
