Abstract—Ammonium-containing germanium and titanium fluoride complexes (NH4)4Li2(AF6)3 and
NH4NaAF6 (A = Ge, Ti) with a heteroatomic cationic sublattice have been synthesized for the first time and
studied by the X-ray powder diffraction method. The unit cell parameters of these compounds are determined.
The IR absorption spectra of the synthesized fluoride complexes recorded in the range 4000–350 cm–1 are inter-
preted.
