The most mercury-rich sodium amalgam, Na11Hg52, is prepared as single crystals by the combination of electrolytic and thermochemical methods. As C. Hoch and A. Simon show in their Communication on page 3262 ff. this amalgam has a close relationship to the chloralkali process and a surprisingly complex structure for a binary compound. Such mercury-rich amalgams serve as models of polar metals in which a transition from the classical metal–metal bonding towards ionic bonding occurs.
