title: Anion-π interactions and positive electrostatic potentials of N-heterocycles arise from the positions of the nuclei, not changes in the π-electron distribution.
abstract: We show that the positive electrostatic potentials and molecular quadrupole moments characteristic of π-acidic azines, which underlie the ability of these rings to bind anions above their centres, arise from the position of nuclear charges, not changes in the π-electron density distribution.
