The important role of π-hole spodium bonding in tri-coordinated planar Hg(ii) complexes is highlighted in this feature article. Selected examples of Hg(ii)X3 structures (X = any atom) illustrate that this noncovalent interaction is relevant as a structural guiding force in crystal structures. For some examples, the interactions have been characterized using the quantum theory of "atoms in molecules" and the noncovalent interaction plot index. Finally, an analysis of the Cambridge structural database revealed that the HgX3 structures are predominantly T-shaped and that they are directional π-hole donors for electron rich atoms.
这篇专题文章强调了π-空穴spodium键在三配位平面汞（II）配合物中的重要作用。汞（II）X3结构（X = 任何原子）的选定示例表明，这种非共价相互作用作为晶体结构中的一种结构导向力是相关的。对于一些示例，已使用“分子中的原子”量子理论和非共价相互作用图指数对相互作用进行了表征。最后，对剑桥结构数据库的分析表明，HgX3结构主要是T形的，并且它们是富电子原子的定向π-空穴供体。
