It is a Bond. Not James Bond but a BANANA BOND.

Diborane (B2H6) is a molecule containing four terminal and two bridging hydrogen atoms (oso known as hydrides). The bonding between boron and the terminal hydrides is fairly conventional. However, the bonding between the boron atoms and the bridging hydrogen atoms is unusual. Having formed two covalent bonds with terminal hydrides, each boron has one electron remaining for additional bonding. The bridging hydrogen atoms each provide one electron each. Thus the B2H2 ring is held together with four electrons. The bonding between the boron atoms and two bridging hydrides of diborane is an example of 3-center-2-electron bonding (3-centre because of 2 B atoms and 1 bridging H atom sharing 2 electrons). This 3-center-2-electron bond is sometimes called a 'BANANA BOND'.
