Phi bond : ウィキペディア英語版
Phi bond

In chemistry, phi bonds (φ bonds) are covalent chemical bonds, where six lobes of one involved atomic orbital overlap six lobes of the other involved atomic orbital. This overlap leads to the formation of a bonding molecular orbital with three nodal planes which contain the internuclear axis and go through both atoms.
The Greek letter φ in their name refers to f orbitals, since the orbital symmetry of the phi bond is the same as that of the usual (6-lobed) type of f orbital when seen down the bond axis.
There is as of 2005 only one known example of a molecule purported to contain a phi bond (a U−U bond, in the molecule U2).
