title: On the existence of intramolecular one-electron Be-Be bonds.
abstract: Although the Be-Be bond is extremely weak in Be2 dimers, we have shown that rather stable Be-Be one-electron sigma bonds are formed upon electron attachment to 1,8-diBeX-naphthalene derivatives. Wavefunction analyses corroborate the formation of Be-Be covalent linkages in which the extra electron is accommodated between the Be atoms as reflected in the dramatic shortening of the Be-Be distance with respect to the corresponding neutral molecule.
