title: Anion-arene adducts: C-H hydrogen bonding, anion-pi interaction, and carbon bonding motifs.
abstract: This article summarizes experimental and theoretical evidence for the existence of four distinct binding modes for complexes of anions with charge-neutral arenes. These include C-H hydrogen bonding and three motifs involving the arene-pi system-the noncovalent anion-pi interaction, weakly covalent sigma interaction, and strongly covalent sigma interaction.
