The molecular structure of the centrosymmetric title compound, [Fe 2 (C 5 H 5 ) 2 (C 24 H 18 )], represents a new application of cross-metathesis for the preparation of functionalized olefins containing two organometallic groups. The two benzene and attached cyclopentadienyl (Cp) rings and the doubl
cis isomers of 2-catecholboryl-1-pinacolboryl-and bis(1,2pinacolboryl)-1,2-bis[4-(trifluoromethyl)phenyl]ethene substitute one another isomorphously in a 1:1 ratio. The molecule has no crystallographic symmetry, with one olefinic site shared equally between superimposed pinacol-and catecholboryls, a
