WebDiborane is a chemical compound that consists of boron and hydrogen atoms and has a molecular formula B 2 H 6. Structure of diborane: The boron atoms has four hybrid orbitals and is considered to be sp 3 hybridized. Three of the orbitals from these four hybrid orbitals have one electron each, and each one of them is an empty orbital.

The structure of diborane has D2h symmetry. Four hydrides are terminal, while two bridge between the boron centers. The lengths of the B–Hbridge bonds and the B–Hterminal bonds are 1.33 and 1.19 Å respectively. This difference in bond lengths reflects the difference in their strengths, the B–Hbridge bonds … See more Diborane(6), generally known as diborane, is the chemical compound with the formula B2H6.
