Molar mass of NH3 = 17.03052 g/mol. 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.

Molecular Weight : 30.87 g/mol CAS-No. FIRST AID MEASURES If inhaled If breathed in, move person into fresh air. The molecule adopts a structure like ethane, with which it is isoelectronic. 39 0 obj <>/Filter/FlateDecode/ID[]/Index[26 26]/Info 25 0 R/Length 72/Prev 23703/Root 27 0 R/Size 52/Type/XRef/W[1 2 1]>>stream This difference is consistent with the highly polar nature of ammonia borane. Additionally, many complexes of borane have been prepared, including borane dimethylsulfide (Me2S→BH3) and borane–tetrahydrofuran (THF→BH3). It has attracted attention as a source of hydrogen fuel, but is otherwise primarily of academic interest. 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. This interaction is called a dihydrogen bond. Ammonia borane (also systematically named amminetrihydridoboron), also called borazane, is the chemical compound with the formula H3NBH3. No predicted properties have been calculated for this compound. endstream endobj startxref ��LHpjap�"�C 9� �G�kL2��E>I�����9YQƛd�P�|����a>g�6�d�1���V`J��1�ۆ��ݕ�. [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. 51 0 obj <>stream CopyCopied, Validated by Experts, Validated by Users, Non-Validated, Removed by Users, Predicted data is generated using the ACD/Labs Percepta Platform - PhysChem Module. 20 repeat units), presumably due to premature precipitation during its formation. If not breathing give artificial respiration Consult a physician. The structure of the solid indicates a close association of the NH and the BH centers. for when the gas is used to fuel motor vehicles. Concentration Borane ammonia complex 13774-81-7 - - - 4. [5] It is more hydrogen-dense than liquid hydrogen and also able to exist at normal temperatures and pressures. The B−H and N−H distances are 1.15 and 0.96 Å, respectively. h޼Umk�0�+�q��z��(�$m��ڕ:���^�%����?�'��5i��=w�;]�S %%EOF [6], Ammonia borane finds some use in organic synthesis as an air-stable derivative of diborane.[7]. 13774-81-7 - WZMUUWMLOCZETI-UHFFFAOYSA-N - Ammonia borane - Similar structures search, synonyms, formulas, resource links, and other chemical information. Generally adduct are more robust with more basic amines. Index-No. Reaction of diborane with ammonia mainly gives the diammoniate salt [H2B(NH3)2]+(BH4)−. Borane tert-butylamine complex is prepared by the reaction of sodium borohydride with t-butylammonium chloride. 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. Convert grams Ammonia to moles or moles Ammonia to grams.
