η5-C5H4R and η4-C4Ph4 rings. The Ph groups do not lie in the C4 planes, and the C4Ph4 ligands constitute four-bladed propellers. The two rings are close to parallel with interplanar angles of 0.4–4.4° except where R = CH(Fc)OH (6.6°) and CFc2OH (12°) which is attributed to steric crowding though this does not affect the ferrocenyl groups to the same extent. When the C atom α to the C5H4 ligand is sp3
