Abstract
(NH4)(2)GeF6 reacts with ammonia to yield NH4[Ge(NH3)F-5] at 280 degre es C. The reaction path was elucidated by in situ time and temperature resolved X-ray pow-der diffraction. NH4[Ge(NH3)F-5] crystallizes isos tructurally to NH4[Si(NH3)F-5] in the tetragonal space group P4/n (No. 85) with lattice constants a = 619.41(1) pm and c = 724.70(1) pm. The germanium atom is coordinated by five fluorine atoms and the nitrogen atom of the ammonia molecule. The ammonium cation is located on the Wy ckoff position (2a) in P4/n. The crystal structure is stabilized by ex tensive hydrogen bonding.
