Ab initio and hybrid density functional techniques were employed to characterize a surprising new class of H-bonded complexes between ions of like charge. Representative H-bonded complexes of both anion–anion and cation–cation type exhibit appreciable kinetic stability and the characteristic theoretical, structural, and spectroscopic signatures of hydrogen bonding, despite the powerful opposition of Coulomb electrostatic forces. All such “anti-electrostatic” H-bond (AEHB) species confirm the dominance of resonance-type covalency (“charge transfer”) interactions over the inessential (secondary or opposing) “ionic” or “dipole–dipole” forces that are often presumed to be essential for numerical modeling or conceptual explanation of the H-bonding phenomenon.

- 21As a check in this case, we also performed full counterpoise (CP)-corrected reoptimizations to verify that possible basis-set superposition errors (i.e., values of 1.29 kcal mol−1 and 0.13 kcal mol−1 at the key stationary points HB2 and TS1, respectively) are insignificant compared to computed well depth. Note that thorough convergence studies of H-bonded clusters (e.g., S. S. Xantheas, J. Chem. Phys. 1996, 104, 8821–8824, and references therein) have indicated that the CP procedure often tends to degrade (rather than “correct”) direct results from the well-balanced aug-cc-pVTZ Dunning-style basis, as used elsewhere in this work.
