Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. Molecular Weight : 30.87 g/mol CAS-No. 13774-81-7 - WZMUUWMLOCZETI-UHFFFAOYSA-N - Ammonia borane - Similar structures search, synonyms, formulas, resource links, and other chemical information. 51 0 obj <>stream The B−H and N−H distances are 1.15 and 0.96 Å, respectively. The structure of the solid indicates a close association of the NH and the BH centers. The colourless or white solid is the simplest molecular boron-nitrogen-hydride compound. Convert grams Ammonia to moles or moles Ammonia to grams. Molar mass of NH3 = 17.03052 g/mol. 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. The closest H−H distance is 1.990 Å, which can be compared with the H−H bonding distance of 0.74 Å. 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:. 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. The data indicate that 8a-8c are essentially linear, high molecular weight materials and that the insoluble polyaminoborane 8d possesses a similar structure but is of lower molecular weight (ca. 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. Ammonia borane has been suggested as a storage medium for hydrogen, e.g. In case of skin contact Wash off with soap and plenty of water.

This difference is consistent with the highly polar nature of ammonia borane. No predicted properties have been calculated for this compound. The molecule adopts a structure like ethane, with which it is isoelectronic.

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. Borane tert-butylamine complex is prepared by the reaction of sodium borohydride with t-butylammonium chloride. Generally adduct are more robust with more basic amines. This interaction is called a dihydrogen bond. FIRST AID MEASURES If inhaled If breathed in, move person into fresh air.
