Conclusions

  1. 1.

    It was shown by the method of IR spectroscopy and x-ray powder patterns that magnesium borohydride hexaammine and beryllium borohydride tetraammine have a “salt-like” structure, and their crystal lattices are constructed from the ions [Mg(NH3)6]2+, [Be(NH3)4]2+, and BH −4 .

  2. 2.

    The parameters of the rhombic cells of [Mg(NH3)6](BH4)2 and [Be(NH3)4](BH4)2 were determined.

  3. 3.

    In the approximation of a “diatomic model” the valence force constants of the Be-N and Mg-N bonds were calculated, and the interatomic distances Be-N and Mg-N in the cations [Be(NH3)4]2+ and [Mg(NH3)6]2+ were determined.
