Molecular Structure
Detailed Description
This colourless solid (cas 13774-81-7) is the simplest molecular boron-nitrogen-hydride compound and has attracted attention as a source of hydrogen fuel. Ammonia borane has been suggested as a storage medium for hydrogen when the gas is used to fuel motor vehicles. It can be made to release hydrogen on heating, being polymerized first to (NH2BH2)n, then to (NHBH)n,which ultimately decomposes to boron nitride (BN) at temperatures above 1000 °C. It is more hydrogen-dense than liquid hydrogen and also able to exist at normal temperatures and pressures. Ammonia borane (cas 13774-81-7)finds some use in organic synthesis as an air-stable derivative of diborane.
