Computational investigations employing Density Functional Theory (SMD(benzene)-M06-2X-D3/6-311+G*) predict that stable metal-free mono (Lewis base)-stabilized borylenes could strongly bind with transition metal (Fe and Ni) complexes. The binding results in increase in the Lewis basicity of the metal centers thus facilitating the formation of metal only Lewis pairs (MOLPs) of the form [L(CO)4Fe→GaCl3] and [L(CO)3Ni→GaCl3] (L=electron donating ligands). Further, the binding of different ligands with the metals as well as bonding in the MOLPs have been further investigated with the help of QTAIM and EDA-NOCV analyses.

碱稳定化硼烯与过渡金属的结合和仅金属路易斯对的形成



采用密度泛函理论 (SMD(苯)-M06-2X-D3/6-311+G*) 的计算研究预测,稳定的无金属单晶 (Lewis base) 稳定的硼烯可以与过渡金属 (Fe 和 Ni) 配合物强烈结合。结合导致金属中心的路易斯碱度增加,从而促进形成 [L(CO)4Fe→GaCl3] 和 [L(CO)3Ni→GaCl3] 形式的仅金属路易斯对 (MOLP)(L=电子供体配体)。此外,在 QTAIM 和 EDA-NOCV 分析的帮助下,进一步研究了不同配体与金属的结合以及 MOLP 中的键合。
