A thorough analysis of the Cambridge Structure Database reveals that intermolecular π-hole/n→π* interactions with carbon monoxide ligands are abundant in the solid state and somewhat directional, particularly with fac-like M(CO)3 fragments (P < 4.0). High level DFT calculations suggest interacting energies up to about -10 kcal mol-1 for adducts of charge neutral complexes.
对剑桥结构数据库的深入分析表明,在固态中,分子间的π-hole/n→π* 与一氧化碳配体的相互作用非常丰富,且具有一定的方向性,特别是具有 fac-like M(CO)3 片段的配合物(P < 4.0)。高水准的 DFT 计算表明,对于电荷中性配合物的加合物,相互作用能高达约-10 kcal mol-1。
