We report the synthesis, characterization and computational analysis of coinage metal-ether complexes supported by N-heterocyclic carbenes (NHC), SIPr and Et2CAAC. The related water adducts are also included. The [(NHC)M]+(M = Cu, Ag, Au) species show the noteworthy ability to bind Et2O and H2O. This interaction towards Et2O and H2O is partly ascribed to a σ-hole bonding with an almost linear disposition, taking advantage of the enhanced σ-hole potential evaluated for such [(NHC)M]+ species. This enhanced ability is larger than those found for non-covalent interactions involving main group species.
我们报道了由氮杂环卡宾（NHC）、SIPr和Et2CAAC支撑的货币金属-醚配合物的合成、表征及计算分析。还包括了相关的水加合物。[(NHC)M]+（M = Cu、Ag、Au）物种表现出与Et2O和H2O结合的显著能力。这种与Et2O和H2O的相互作用部分归因于一种几乎呈线性排列的σ-空穴键合，这得益于对这类[(NHC)M]+物种评估出的增强的σ-空穴势。这种增强的能力比涉及主族物种的非共价相互作用所发现的能力更大。
