[5] It is more hydrogen-dense than liquid hydrogen and also able to exist at normal temperatures and pressures. It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound.

Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. This difference is consistent with the highly polar nature of ammonia borane. It can be made to release hydrogen on heating, being polymerized first to (NH2BH2)n, then to (NHBH)n,[4] which ultimately decomposes to boron nitride (BN) at temperatures above 1000 °C. No predicted properties have been calculated for this compound. H dihydrogen interaction is investigated at the M06L/6-311+G(d,p) level of density functional theory. Borane tert-butylamine complex is prepared by the reaction of sodium borohydride with t-butylammonium chloride. EC-No. Generally adduct are more robust with more basic amines. for when the gas is used to fuel motor vehicles. In case of skin contact Wash off with soap and plenty of water.

Index-No. Many analogues have been prepared from primary, secondary, and even tertiary amines: The first amine adduct of borane was derived from trimethylamine. Ammonia borane is the main product when an adduct of borane is employed in place of diborane:[1]. For clusters containing up to six monomers, ladder, cyclic, stacked, cross-stacked, end-on, mixed and hexagonal configurations have been screened for their energetic stability. The closest H−H distance is 1.990 Å, which can be compared with the H−H bonding distance of 0.74 Å. Reaction of diborane with ammonia mainly gives the diammoniate salt [H 2 B(NH 3) 2] +, (BH 4) −.Ammonia borane is the main product when an adduct of borane is employed in place of diborane: BH 3 + NH 3 → BH 3 NH 3 + THF Properties and structure. 13774-81-7 - WZMUUWMLOCZETI-UHFFFAOYSA-N - Ammonia borane - Similar structures search, synonyms, formulas, resource links, and other chemical information.
