does not participate in halogenbonding) enables estimation of the contribution of this interaction to the free energy of anion binding. Evidence for attractive contacts betweenanions and electron-deficient arenes arising from the use of perfluoroarene-functionalized ureas as control receptors is also discussed. The magnitude of the free energy contribution of halogenbonding depends both on the geometric
