The mercury‐richest europium amalgam Eu 10 Hg 55 was synthesized by isothermal electrocrystallization from a solution of EuI 3 · 8DMF in DMF on a reactive mercury cathode. The crystal structure shows remarkable complexity and polar metal–metal bonding. Closely related to the structures of mercury‐rich amalgams A 11– x Hg 55+ x ( A = Na, Ca, Sr), it shows underoccupied Hg positions along [00 z ]. Eu 10 Hg 55 can be described as hettotype structure of the Gd 14 Ag 51 structure type.
