2-[(Ferrocen-1-yl)(hy-droxy)meth-yl]prop-2-ene-nitrile.

In the title ferrocene derivative, [Fe(C5H5)(C9H8NO)], the dihedral angle between the ene-nitrile group and the substituted cyclo-penta-dienyl ring is 71.2 (1)°. The cyclopentadienyl rings of the ferrocene moiety are arranged in an eclipsed conformation. The hy-droxy group, and the corresponding methine H atom, are disordered over two sets of sites with site-occupancy factors of 0.744 (4) and 0.256 (4). An intra-molecular C-H⋯O close contact is observed. In the crystal, O-H⋯N hydrogen bonds form a C(6) chain along [100].
