Abstract
The melting diagram of the quasi-binary system NH3-HF between the limits NH4HF2 and HF was redetermined. The compounds NH3 · 4HF, NH3 · 5HF and NH3 · 8HF with melting points of 26, -14 (dec.) and -95 °C (dec.), respectively, were established as the stable phases. Their crystal structures were determined as those of ammonium hydrogen fluorides NH4[F(HF)4], NH4[F(HF)4] and NH4[HF2(HF)3] · 3HF with extended N-H···F and F-H···F hydrogen bonding.Keywords
