Rings around rings : Cyclotrimerization of a hexapentaene‐extended quinocumulene led to the novel tricyclobutabenzene derivative shown. Its molecular structure reveals a considerably distorted propeller configuration that deviates largely from the ideal C 3 symmetry. Moderate bond alternation is evident in the central benzene ring.
