Abstract

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.
