The closest H−H distance is 1.990 Å, which can be compared with the H−H bonding distance of 0.74 Å. Generally adduct are more robust with more basic amines. CopyCopied, WZMUUWMLOCZETI-UHFFFAOYSA-N The H atoms attached to boron are hydridic and those attached to nitrogen are somewhat acidic. This interaction is called a dihydrogen bond. %PDF-1.4 %���� Ammonia borane (also systematically named amminetrihydridoboron), also called borazane, is the chemical compound with the formula H3NBH3. Many analogues have been prepared from primary, secondary, and even tertiary amines: The first amine adduct of borane was derived from trimethylamine. It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. Variations are also possible for the boron component, although primary and secondary boranes are less common.[8].

Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. The B−N distance is 1.58(2) Å. The structure of the solid indicates a close association of the NH and the BH centers. h޼Umk�0�+�q��z��(�$m��ڕ:���^�%����?�'��5i��=w�;]�S Click to predict properties on the Chemicalize site, For medical information relating to Covid-19, please consult the, ACD/Labs Percepta Platform - PhysChem Module, Compounds with the same molecular formula, Search Google for structures with same skeleton.

[2][3] The original crystallographic analysis of this compound reversed the assignments of B and N. The updated structure was arrived at with improved data using the technique of neutron diffraction that allowed the hydrogen atoms to be located with greater precision. It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. Additionally, many complexes of borane have been prepared, including borane dimethylsulfide (Me2S→BH3) and borane–tetrahydrofuran (THF→BH3). EC-No. [5] It is more hydrogen-dense than liquid hydrogen and also able to exist at normal temperatures and pressures. Synthesis. Ammonia borane (also systematically named amminetrihydridoboron), also called borazane, is the chemical compound with the formula H 3 NBH 3.The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound. Borane tert-butylamine complex is prepared by the reaction of sodium borohydride with t-butylammonium chloride.

FIRST AID MEASURES If inhaled If breathed in, move person into fresh air. Ammonia borane is the main product when an adduct of borane is employed in place of diborane:[1]. Reaction of diborane with ammonia mainly gives the diammoniate salt [H2B(NH3)2]+(BH4)−. Its gaseous decomposition products have a very low molecular weight, which makes AB attractive in a propulsion application, since specific impulse is inversely related to the molecular weight of the products.

The molecule adopts a structure like ethane, with which it is isoelectronic. Ammonia borane (NH3BH3; AB), which has a hydrogen content of 19.6% by weight, has been studied recently as a potential means of hydrogen storage for use in fuel cell applications. Consult a physician. Ammonia borane has been suggested as a storage medium for hydrogen, e.g. No predicted properties have been calculated for this compound.

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.
