[6-(Hy­droxy­meth­yl)pyridin-2-yl]methyl ferrocene-1-carboxyl­ate

Abstract

The crystal structure of the title ferrocene derivative, [Fe(C₅H₅)(C₁₃H₁₂NO₃)], shows strong inter­molecular O—H⋯N hydrogen bonds between the alcohol function and the pyridine group of a neighbouring mol­ecule, while the pyridine function forms another hydrogen bond with the alcohol function of another neighbouring mol­ecule, resulting in the formation of chains along the a-axis direction.

Comment

Ferrocene derivatives are known to exert antiproliferative effects on cancers (Hillard & Jaouen, 2011) and, in this paper, the molecular structure of a ferrocene derivative, {6-(hydroxymethyl)pyridin-2-yl}methyl ferrocene-1-carboxylate, is presented. However, a biological evaluation was not possible due to the low water-solubility of the compound.

The title compound is obtained following a previsouly published procedure (Izumi et al., 1984; Izumi et al., 1988) using ferrocenoyl chloride and 2,6-pyridinedimethanol in the presence of triethylamine. After purification, the compound crystallizes in the tetragonal space group P 4₁2₁2 with eight molecules per unit cell. These molecules are pilled along the c axis (c = 53.351 (4) Å). In the solid state, the ferrocene adopts an eclipsed conformation, and the pyridyl substituent is positionned perpendicular to the plane of the η⁵-C₅H₄COOCH₂– moiety. Otherwise, the metrical parameters are normal and compare well to those of analogous functionalized-ferrocenyl molecules (Auzias et al., 2008; Auzias et al., 2009).

In the crystal packing, the pyridyl and the alcohol functions are involved in strong H-bonded interactions with two neighbouring symmetry-related molecules: The N—O separation being 2.827 (4) Å with the O—H···N angle being 159 (6)°.

Experimental

Crystals suitable for X-ray diffraction analysis were obtained, after days, by slow diffusion of diethyl ether into a chloroform solution of the title complex.

Refinement

All H atoms, except for OH, were included in calculated positions (C—H = 0.93 Å for C_arom, 0.97 Å for CH₂) and treated as riding atoms with the constraint U_iso(H) = 1.2 U_eq(carrier) applied.

Special details

Experimental. A crystal was mounted at 173 K on a Bruker SMART CCD PLATFORM using Mo Kα graphite monochromated radiation. Image plate distance 70 mm, φ oscillation scans 0 - 200°, step Δφ = 0.5°, 3 minutes per frame.

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.
