Research in the field of M⋯H–X interactions has found application in X–H bond activation, crystal engineering and the construction of supramolecular structures, fast ligand exchange phenomena in solution and biological chemistry. The wealth of literature available on inter- and intramolecular M⋯H–B (M = Cu^I, Ag^I) associations allow their grouping and subclassification based on inner sphere complex coordination. An insufficient number of M⋯H–X (X = N, O, Si) interactions, suitably metrically characterized for the purpose of critical comparison, is known. The few well-studied examples of M⋯H–C (M = Cu^I/II, Ag^I) interactions exhibit certain close analogies with, but also largely diverging binding situations from, the B–H benchmarks. Attachment of highly polarized Zn^IIH or Al^IIIH units to Cu^I complex fragments adds a new dimension to the M⋯H–X intermolecular interaction phenomenon, taking it into unexplored territory.

M⋯H–X相互作用领域的研究已发现可用于X–H键活化，晶体工程和超分子结构的构建，溶液和生物化学中的快速配体交换现象。关于分子内和分子内M⋯H–B（M = Cu ^I，Ag ^I）关联的大量文献允许根据内球复杂配位对它们进行分组和分类。已知有足够数量的M–H–X（X = N，O，Si）相互作用不足以恰当地进行度量以进行关键比较。几个经过充分研究的M⋯H–C的例子（M = Cu ^{I / II}，Ag ^I）互动展示出与B–H基准之间的某些相似之处，但绑定情况也大不相同。将高度极化的Zn ^II H或Al ^III H单元连接到Cu ^I复杂片段上，为M⋯H–X分子间相互作用现象增加了新的维度，使其进入了尚未探索的领域。
