Borazine or borazole (B3N3H6) is known as inorganic benzene. It is also called Because the structure of borazine is similar to that of benzene. It is also isoelectronic and isosteric with benzene.
Like carbon is benzene, both N and B in borazine are sp2 hybridized. Each N has a p-orbtal which is perpendicular to the a-bonding orbitals and contains a lone pair of electrons. In contrast, each B has an empty p-orbitals which is also perpendicular to the plane of the ring. Thus, the x-bonding in borazine is dative and it arises from the sideways overlap of fully filled orbitals of N and empty p-orbitals of B.
Preparation of borazine: At low temperature, diborane combines with ammonia to form an addition compound.
When this addition compound is heated to 473 K, it decomposes to form a volatile compound called borazine.
