(E)-1-Ferrocenyl-3-[2-(2-hy­droxy­eth­oxy)phen­yl]prop-2-en-1-one

In the title compound, [Fe(C₅H₅)(C₁₆H₁₅O₃)], the cyclo­penta­dienyl rings are in an eclipsed conformation and the benzene ring makes dihedral angles of 10.84 (9) and 12.35 (9)°, respectively, with the substituted and unsubstituted cyclo­penta­dienyl rings. In the crystal, mol­ecules form inversion dimers through pairs of O—H...O hydrogen bonds. Weak C—H...O hydrogen bonds are observed between the dimers.

The title compound, C₁₉H₁₈O₃, crystallizes with three mol­ecules (A, B and C) in the asymmetric unit. The carbonyl O atom shows positional disorder over two sites in mol­ecules A and B; the site-occupancy ratios are 0.76 (3):0.24 (3) and 0.86 (3):0.14 (3), respectively. The ethyl­ene fragments in each mol­ecule have an E conformation, while the C—O—C—C torsion angles indicate near planarity. The dihedral angles formed by the aromatic rings are 20.0 (1), 23.7 (1) and 16.1 (1)° for mol­ecules A, B and C, respectively. Intra­molecular C—H...O hydrogen bonds occur in each mol­ecule.
