Antielectrostatically hydrogen bonded anion dimers: counter-intuitive, common and consistent

White, Nicholas


The Cambridge Structural Database was surveyed for antielectrostatically hydrogen bonded anion complexes. The survey revealed that these complexes are relatively common, e.g. half of all structurally characterised bicarbonate anions are present as dimers. Generally, the bonding is surprisingly homogenous with O⋯O contacts close to 2.6 Å for all anions. Distances are similar in length to, or slightly shorter than, those in carboxylic acid dimers, which do not have to contend with Coulombic...[Show more]
