Explain structures of diborane

Explain structures of diborane.

  • In the structure of diborane, the four terminal hydrogen atoms and the two boron atoms lie in one plane.
  • Above and below this plane, there are two bridging hydrogen atoms.
  • The four terminal B-H bonds are regular two centre-two electron bonds while the two bridge (B-H-B) bonds are different and can be described as three centre -two electron bonds or banana bond.
