The dimeric cyclophanes 8 and 9 were observed to form roughly rectangular a small cavity, with the DTTA rings at two of the comers. The DTTA ring of the monomeric phane 6 was observed to be significantly distorted when compared with the structures of less constrained DTTA's, and ab initio calculations indicated that the phane 7, which has a shorter bridge, but for which there is no X-ray structure, is even more highly strained.
