Аннотация: The salts (NH₄)₂(HF₂)(NO₃) and K₃(HF₂)(NO₃)₂ were isolated by crystallization from aqueous bifluoride and nitrate solutions. The crystal structures of the ammonium and potassium salts contain short hydrogen bonds in bifluoride anions (HF₂)⁻ with F···F distances of 2.277(5) and 2.237(1)Å, respectively, and the latter is the shortest among all ever reported hydrogen bonds in metal bifluorides.

Ключевые слова: bifluoride, nitrate, potassium, ammonium, hydrogen bond, crystal structure.
