Amalgam (chemistry) but can be worked with under dry nitrogen. The Hg-Hg distance is around 300 picometres, Hg-K around 358 pm. Phases KHg and KHg are also known; rubidium, strontium and barium undecamercurides are known and isostructural. Sodium amalgam (NaHg) has a different structure, with the mercury atoms forming hexagonal layers, and the sodium atoms a linear chain which fits into the holes in the hexagonal layers, but the potassium atom is too large for this structure to work in KHg. Sodium amalgam is produced as a byproduct of the chloralkali process and used as an important reducing agent in organic and
