To check the influence of substituents on the bonding of the 12π‐perimeter of s ‐indacene , a tetraalkyl derivative, the title compound 1 , was synthesized. 1 , red needles, is weakly paratropic. Crystal structure analysis and NMR investigations indicate a delocalized or a localized π‐electron system with only a small energy barrier between the π‐bond isomers.
