With the Hückel method using a bond-length-dependent coupling (β), a description is given for the various C 2ν geometries for odd-membered cyclic 4n π electrons under cross-linking, so we arrive at a more general conclusion with respect to their antiaromatic behavior. Model systems are introduced to
