The crystal structures of bisquadricyclanylidene 1 , 7‐quadricyclanylidenenorbornadienes 2 and 3 are solved by X‐ray diffraction analyses. The bond lengths of the cyclopropyl moieties of 1 , 2 and 3 are compared with several other quadricyclanylidene derivatives, and the differences are analyzed by computational models. The results showed that the variation of bond lengths in this series of compounds is related to the electronic nature of substituents.
