摘要：
The synthesis and X-ray diffraction study of compounds K2-x (NH4)xZrF(6) (0 < x < 2) were carried out. In all crystals of mixed composition, potassium cations are isomorphously replaced by ammonium cations. The compounds with x < 0.5 are isostructural to K2ZrF6 and those with x > 1.5, to (NH4)(2)ZrF6. At 0.5 < x < 1.5, the structures are built of linear polymeric chains formed by edge-sharing Zr dodecahedra. The distribution of potassium and ammonium cations over the cationic positions was considered.
