Abstract:
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.
