As we learnt in 

Reaction of diborane with ammonia -

Gives borazine (B3N3H6), known as inorganic benzene

- wherein

3B_{2}H_{6}+6NH_{3}\rightarrow 3\left [ BH_{2}\left ( NH_{3} \right )_{2} \right ]^{+} \left [ BH_{4} \right ]^{-} \overset{Heat}{\rightarrow}2B_{3}N_{3}H_{6}+12H_{2}

 

Borazine (also called inorganic benzene) is B3N3H

Clearly it has same number of atoms and same number of electrons. It is both isosteric and isoelectronic with benzene.
