Tetraammineberyllium halides and pseudo-halides [Be(NH3)4]X2 (X = Cl, Br, I, CN, SCN, N3) as well as Be(NH3)2F2 have been prepared from beryllium metal and NH4X or NH4F in liquid ammonia at ambient temperature, respectively. Diammineberyllium halides Be(NH3)2X'2 (X' = Cl, Br, I) were synthesized at 300 °C from Be and NH4X'. The obtained compounds were characterised via X-ray diffraction, and IR and Raman spectroscopy and their thermal decomposition was studied by TGA.
