The title compound was synthesized by refluxing a tetrahydrofuran solution of acetylferrocene and ethyl picolinate in the presence of sodium ethoxide (1:1:1) for 4 h, as described previously (Reference?). Red crystals of (I) were obtained by slow evaporation from a CH2Cl2–petroleum ether (Ratio?) solution (m.p. 417.6–418.4 K). Spectroscopic analysis: IR (KBr, ν, cm−1): 3438.84 (m, OH), 3101.12 (s, CH), 1593.7 (vs, O═C), 1546.10 (vs, C═C); 1H NMR (600 MHz, CDCl3, δ, p.p.m.): 16.254 (1H, s, OH), 8.731, 8.149, 7.881, 7.440 (4H, 4m, pyridyl), 7.098 (1H, s, CH), 4.993, 4.599 (2H, 2H, 2m, C5H4), 4.246 (5H, s, C5H5).
All H atoms were placed in geometrically idealized positions and were treated as riding atoms, with C—H distances in the range 0.93–0.98 Å and O—H = 0.82 Å. Uiso(H) values were set at 1.2Ueq(C) and 1.5Ueq(Cmethyl, O).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Enaminones are important ligands in coordination chemistry (Doherty et al., 1999; Kim et al., 2001; Li et al., 2004). In continuation of our investigation of the chemistry of ferrocenyl enaminones, we have prepared the title compound, (I), as an intermediate, via the Claisen condensation of acetylferrocene and ethyl picolinate (Shi et al., 2004, 2005).
Ccompound (I) has been shown by 1H NMR spectroscopy to exist in solution in the enol and not the keto form. IR spectroscopy shows only the enol form in the solid state; this has been further confirmed in the present study of its crystal structure (Fig. 1).
As also noted in the related compound 1-ferrocenyl-3-hydroxylbut-2-en-1-one, (II) (Bell et al., 1992), the O═C—C═C—O fragment of the molecule of (I) is planar. The bond lengths indicate electron delocalization (Gilli et al., 2000). The O═C—C═C—O plane is twisted with respect to the pyridyl and cyclopentadienyl rings by 3.3 (2) and 9.4 (2)°, respectively. The two cyclopentadienyl rings in the ferrocenyl group are parallel [dihedral angle 1.5 (3)°] and adopt a staggered conformation. The C13—C14 bond, which is typical of a single bond (Csp2—Csp2), suggests that the pyridyl ring is not involved in the conjugation of the O═C—C═C—O moiety.
Unlike (II), as well as the intramolecular hydrogen bond [O—H···O═C], intermolecular hydrogen bonds [C—H···O═C] are also present in the crystal structure of (I) (Fig. 2, Table 2).
