Racemic 1-ferrocenyl- 1-phenylethanol, [(CsHs)Fe-
(CsHa)]CPhMeOH (I), crystallizes as discrete molecules
which are not involved in hydrogen bondinog; the shortest
intermolecular O-..O contact is 3.768(3) A and the hydroxyl
H atom is orientated towards the unsubstituted cyclopentadienyl ring. Ferrocenyl(diphenyl)methanol,
[(CsHs)Fe(CsHa)]CPh2OH (II) is hydrogen bonded to
form centrosynunetric dimers with O...O 2.816(1) and
H...O 2.52 ]k. Ferrocene-l,l~-diylbis(diphenylmeth -
anol), Fe[(CsHa)C(Ph)2COH]2 (III) crystallizes as a
dimeric aggregate with the Fe atoms on twofold crystallographic symmetry axes and the four O atoms defining a folded trapezium with O...O 2.762(2), 2.714(2)
and 2.865(2) A,. The four hydroxyl groups are disordered
equally over two orientations such that there are two halfoccupancy H-atom sites between each hydrogen-bonded
oxygen pair.
