is diborane electron deficient
Bonding diagram of diborane (B 2 H 6) showing with curved lines a pair of three-center two-electron bonds, each of which consists of a pair of electrons bonding three atoms, two boron atoms and a hydrogen atom in the middle.Diborane adopts a D 2h structure containing four terminal and two bridging hydrogen atoms.The model determined by molecular orbital theory indicates that the bonds between boron and the terminal hydrogen atoms are conventional 2-center, 2-electron covalent bonds.iborane adopts a D 2h structure containing four terminal and two bridging hydrogen atoms.
