A mixed trianion consisting of one germyl anion and two anions delocalized on conjugated carbon ring skeletons was synthesized by the trimerization of the germanium analogue of anthryl anion, which exhibits high germylene character. In addition, the dianion, the dimer of the 9‐germaanthracene radical anion, having two germyl anions, was isolated. More information can be found in the Communication by S. Fujimori, Y. Mizuhata, and N. Tokitoh on page 6284.
