I. The crystal and molecular structures of a dimer of a cyclobutadiene derivative. The molecular structure of this compound, previously suggested by other chemical work, has been conclusively established. Bond lengths and angles within the tricyclooctadiene skeleton were established with a precision exceeding that of any other study of a substituted cyclobutane and of any save one study of a substituted cyclobutene. Lengthening of the average C-C single and double bond in a C_4 ring is confirmed, and a shortening of the average external bond is also found. All bonds are normal (considering the above effects) except a C-C single bond in the configuration F-C-C-F, which is found to be 1.500 ± 0.009 Å rather than the expected 1.58 Å. The diff...
