π-Hole/n→π* interactions with acetonitrile in crystal structures†
Abstract
A thorough analysis of the Cambridge Structure Database shows that π-hole/n→π* interactions with acetonitrile are abundant in the solid state, particularly when acetonitrile is coordinated to a metal. The interaction is weakly directional (P ≤ 1.5) and high level computations suggest a complexation energy of about −5 kcal mol−1.
