Abstract top

In the title compound, [Fe(C5H5)(C14H10NO3)], one cyclopentadiene ring is substituted and one is unsubstituted. The two rings are almost parallel and are eclipsed and ordered. The conjugated substituent is slightly twisted with respect to the cyclopentadiene ring. The crystal structure contains four intermolecular C-H...O hydrogen-bonds in the range 3.324 (3)-3.539 (3) Å and one [pi](aryl ring)-[pi] (Cp ring) stacking interaction with a ring-centroid distance of 3.894 (2) Å.

Comment top

α, β-unsaturated ketones are important as intermediates in many addition reactions and they are also used widely in synthesizing of spice and medicament and materials (Mrisra et al., 1973; Zhai et al.,1999; Liu et al., 2001, 2003; Yarishkin et al., 2008). Since the discovery of ferrocene (Kealy & Pauson, 1951), ferrocene has played an important role in the development of electronic structures of organometallic compounds and materials chemistry. A considerable number of ferrocene derivatives have been prepared directly or indirectly from ferrocene and their properties have been extensively studied. As part of our search for new biological active compounds (Liang et al., 1998; Shi et al., 2004; Liu et al., 2008), we report herein the synthesis and crystal structure of the tltle compound.

The molecule of the title compound exists as the most stable configuration of (E)-isomer (Scheme 1, Fig.1, Table 1). The Cps ring is connected to the phenyl group through the C6—C7=C8—C9—C10 chain with the C=C bond length being 1.330 (3) Å and the three single Csp2—Csp2 bond lengths ranging from 1.472 (3) to 1.477 (3) Å, which are the same with the result of our early works (Liu et al., 2008). This rang compares well with the statistical values for such bond lengths in conjugated C=C—C(=O)—C system [1.464 (18) Å] and for Csp2—Caryl bonds (lower quartile 1.472 Å) (Allen et al., 1987). The C9=O3 and C4—N1 bond distances are 1.226 (3) and 1.473 (3) Å, The Cp and Cps rings are nearly parallel [dihedral angle 0.99 (11)°]. The dihedral angle between the benzene ring and Cps ring is 6.6 (10)°, which is in agreement with the literature (Harrison et al., 2006). The nitro group is well ordered and makes a dihedral angle of 4.57 (3)° with respect to the benzene ring.

In its packing structure, along b axis two neighboring molecules are linked into R22(12)R22(12)R22(12) (Bernstein et al., 1995) dimer by two pairs of C14–H14(Cps)···O2(nitro) and C7–H7···O3=C inter-molecular hydrogen-bonds and the two neighboring dimers are linked into R22(10) ladder-shape by two C3–H3(aryl)···O1(nitro) inter-molecular hydrogen-bonds, thus forming cross edge-fused R22(10)R22(12)R22(12)R22(12) sheet (Fig. 2, Table 2). At same time, along c axis the two neighboring dimers linked into R44(16) chains and the neighboring chains above and below are assemble into a block via π(aryl ring)···π(Cp ring) inter-molecular stacking interactions (the corresponding ring-centroid separation is 3.894 (2) Å) (Fig. 3). All of the above mentioned inter-molecular hydrogen-bonds link the molecules into a three-dimensional structure of considerable complexity.

Experimental top

Acetylferrocene (1.98 g, 0.01 mol) in ethanol (25 ml) was mixed with 3-nitrobenzaldehyde (1.51 g, 0.01 mol) in ethanol (25 ml) and the mixture was treated with an aqueous solution (20 ml) of potassium hydroxide (20 ml, 5%). The resulting mixture was stirred well and left for 24 h, and the solid product was collected by filtration and dried. Crystals of the product were obtained from ethanol recrystallization (yield 80%; m.p. 463 K). Analysis, found (calculated) for C19H15O3NFe (%): C 63.16 (63.29), H 4.16 (4.12), N 3.88 (3.65).

Refinement top

After their location in a difference map, all H atom were fixed geomerically at ideal positions and allowed to ride on the parent C atom.with C—H distances of 0.93 Å(CH) or 0.98 Å (ferrocenyl), and with Uiso(H) values of 1.2Ueq(C).

Special details top

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.
