A process for producing diborane is provided which includes mixing boron halide with borohydride ionic liquid for providing a liquid reaction mixture, the liquid reaction mixture chemically reacting for producing gaseous diborane. There is also provided a related composition for producing diborane which includes boron halide and borohydride ionic liquid. Solvents are not needed in the mixture or in the composition to produce the diborane.
