title: Should "anion-π interactions" be called "anion-σ interactions"? A revision of the origin of some hole-bonds and their nomenclature.
abstract: The so-called anion-π interactions are dissected to test if indeed the π system of the aromatic ring is the reason for the bond. In contrast, due to σ-holes the σ system is found to be responsible for a "pseudo-π hole" interaction. Models that form genuine anion-π bonds are discussed.
