Cs2Hg27, das quecksilberreichste Amalgam – ein naher Verwandter der Bergman‐Phasen

Cs₂Hg₂₇, the Mercury‐richest Amalgam with Close Relationship to the Bergman Phases By electrolyzing a solution of cesium iodide in N,N‐dimethylformamide at 2 °C on a mercury cathode the amalgam Cs₂Hg₂₇ can be synthesized. It crystallizes in an own cubic structure type (space group , a = 16.557(4) Å). The structure can be rationalized by a system of concentrical polyhedral spheres, in close analogy to the Bergman phases.
