Abstract
Over the last ten years, a few examples of so-called non-covalent structures of negative ions have been found, the geometry of which differs significantly from the geometry of the original molecules. In particular, the lengths of carbon-halogen bonds reach 2.7–3 Å, and the halogen atom itself can circle the hydrocarbon skeleton of the anion, the so-called roaming effect. Such non-covalent structures can have a significantly higher electron affinity than the original molecules.
