The first isolable, crystalline compound containing the bishomoaromatic anion bicyclo[3.2.1]octa‐2,6‐dienide, the tetramethyl‐ethylenediamine adduct of the title compound 1 , has C s symmetry in solution. In crystalline 1 , however, the lithium is bonded unsymmetrically to all five sp 2 C‐atoms. The C 2 ‐ and C 3 ‐bridges are surprisingly close to each other, as is required for bishomoaromaticity; lithium has the unusual coordiation number 7.
