Reaction Steps: Diborane reacts with ammonia at room temperature to form the ionic adduct $[B{H}_2(N{H}_3{)}_2{]}^{+}[B{H}_4{]}^{-}$ (A).

Formation of B: On heating, this ionic compound decomposes into Borazine ($B_3{N}_3{H}_6$) (B) and flammable hydrogen gas ($H_2$) (C).

Structure of B: Borazine (inorganic benzene) has a planar hexagonal ring structure with sp² hybridized Boron and Nitrogen atoms.

Planar Atoms: Because the molecule is entirely co-planar, all 3 Boron, 3 Nitrogen, and 6 Hydrogen atoms (totaling 12 atoms) lie in the single same plane.
