A variety of ferrocenophanes containing two bridges and two six-membered condensed-rings have been synthesized. Three of them (XII, XV and XVI) are identical to the compounds which we previously reported to be tetrabridged ferrocenophanes. Thus, the structures of the products formed by cyclization of [4][3][4]ferrocenophanebutanoic acids (I and II) have been determined, and the description in the previous
