Abstract Bonding in FHF − , (HF) 2 , and FHF is compared from the molecular orbital and electrostatic bonding viewpoint. The electrostatic force is dominant in the formation of FHF − and HF dimer. Exchange repulsion dominates in preventing the formation of FHF and leads to a D ∞h transition state for H exchange. At the D ∞h stationary points for FHF − and FHF the electronic structure can be understood using delocalized symmetry orbitals, but this delocalization is not the primary driving force along the potential energy surface leading to these structures. © 2004 Wiley Periodicals, Inc.
