The cis,syn,cis ‐tricyclic [2+2]‐dimer of cyclooctatetraene, C 16 H 16 , crystallizes in space group Pca 2 1 with two molecules in the asymmetric unit. An extensive network of weak C—H⋯π(Czdbnd;C) interactions between the two independent molecules, A and B , as well as A ⋯ A and B ⋯ B interactions, are observed in the supramolecular assembly. The C—H groups point more towards one C atom than to the centre of the Czdbnd;C bond. Notable among the interactions are bifurcated (cyclobutane)C—H⋯Czdbnd;C contacts that span transannularly the eight‐membered ring.
