The length of the carbon bridge between the two positively charged nitrogen centers in dication 1 influences the coordination sphere of the Bi center in the title anion. The change from square‐pyramidal ( n = 3, shown schematically on the right) to pentagonal‐pyramidal ( n = 2) is attributed to the formation of NHO hydrogen bonds.
