Preferred Label : multi-centre bond;
IUPAC definition : Representation of some molecular entities solely by localized two-electron two-centre
bonds appears to be unsatisfactory. Instead, multi-centre bonds have to be considered
in which electron pairs occupy orbitals encompassing three or more atomic centres.
Examples include the three-centre bonds in diborane, the delocalized π-bonding of
benzene and bridged carbocations.;
