- Four-center_two-electron_bond abstract "A four-center two-electron bond is a type of chemical bond in which four atoms share two electrons in bonding, with a net bond order of ½. This type of bonding differs from the usual covalent bond, which involves two atoms sharing two electrons (2c-2e bonding).Four-center two-electron bonding is postulated in certain cluster compounds. For instance, the borane B6H−7 anion, is a B6H2−6 octahedron with an additional proton attached to one of the triangular faces. As a result the octahedron is distorted and a BBBH rhomboid ring can be identified in which this 4c-2e bonding takes place. This type of bonding is associated with electron deficient rhomboid rings in general and is a relatively new research field, fitting in with the already well established three-center two-electron bond.An example of a purely organic compound with four-center two-electron bonding is the adamantyl dication. The bond joins the four bridgehead atoms in a tetrahedral geometry.Tetracyanoethylene forms a dianionic dimer in which the two alkenes are joined face-to-face by a rectangular four-center two-electron bond. Various solid salts of this dianion have been studied to determine bond strengths and vibrational spectroscopic details.".
