Abstrakt: 1.It was shown by the method of IR spectroscopy that under the action of ammonia on aluminum borohydride, monochloroborohydride, and dichloroborohydride, there is a nonsymmetrical cleavage of the A1H2B groups with the formation of “salt-like” compounds, constructed from [A1(CH3)6]3+, Cl-, and BH4-.2.The parameters of the rhombic cells of the compounds A1(BH4)3·6NH3, A1(BH4)2C1·6NH3, A1(BH4)C12·6NH3, and A1C13·6NH3.3.The valence force constant of the Al-N bond was calculated in the approximation of a “diatomic” model, and the Al-N interatomic distance was determined in the octahedron [A1(NH3)6]3+.
