A solution of ferrocenoylacetone (0.2 g, 0.74 mmol), p-bromoaniline (0.13 g, 0.74 mmol) and a catalytic trace amount of p-TsOH in 30 ml of toluene was refluxed with a Dean-Stark apparatus to remove water for 12 h. The solvent was evaporated under vacuum, and the crude reaction mixture was submitted to
(silica gel 60, hexane:diethyl ether = 1:1 v/v). The title compound crystallizes from the solvent mixture to give red crystals (60%), mp. 168.9–171.0 °C.IR (KBr) cm-1: 3079 (NH), 1606 (C=O), 1570 (C=C).

The NH hydrogen atom was located in a difference Fourier map and geometrically refined with Uiso(H) = 1.2Ueq(N). The other H atoms positions were calculated after each cycle of
using a riding model with C—H distances in the range 0.95—0.98 Å and Uiso(H) = 1.2Ueq(C).Ferrocenes containing enaminones have attracted interest because they can be used as good chelating ligands for transition metals (Shi et al., 2004, 2005, 2008). On the other hand, anions generated from these molecules offer alternatives to conventional ligands (cyclopentadienyl anions) in the formation of transition metal complexes for olefin polymerization catalysts (Ye et al., 2008).
The title compound, [Fe(C5H5)(C15H13BrNO)], (I), is a Schiff base molecule resulting from the reaction of ferrocenoylacetone and 4-bromoaniline. It crystallizes in the monoclinic
P21/c and its contains only one title molecule (Fig. 1).The distances between the cyclopentadienyl ring centroids and the Fe atom are 1.644 Å and 1.634 Å, respectively. The cyclopentadienyl rings of the ferrocenyl group are parallel with a dihedral angle of 1.9 (3)° between the corresponding least-squares planes. These metrical parameters are typical of the η5···Fe···η5 coordination of the ferrocenyl moiety. The O1—C11—C12—C13—N1 skeleton is coplanar (rms deviation = 0.005 Å). The C≐O, C≐C and C≐N bond lengths are intermediate between their corresponding double and single bonds indicating that the π-system is partially delocalized in the framework. Likewise, the skeleton is nearly coplanar with the C5H4 ring with an angle of 6.9 (2)° between the mean planes. On the other hand, the angle between the least-squares planes of O1—C11—C12—C13—N1 and the bromophenyl ring C16/C20 is 33.8 (1)° out of the plane showing the lack of conjugation between both systems.
The molecular structure of the enaminone-containing compound is also stabilized by an intramolecular N-H···O hydrogen bond between the amine and the carbonyl groups (Table 1). This feature has been previously described by Fuentealba et al. (2008).

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. |

Ferrocenes containing enaminones have attracted interest because they can be used as good chelating ligands for transition metals (Shi et al., 2004, 2005, 2008). On the other hand, anions generated from these molecules offer alternatives to conventional ligands (cyclopentadienyl anions) in the formation of transition metal complexes for olefin polymerization catalysts (Ye et al., 2008).
The title compound, [Fe(C5H5)(C15H13BrNO)], (I), is a Schiff base molecule resulting from the reaction of ferrocenoylacetone and 4-bromoaniline. It crystallizes in the monoclinic space group P21/c and its asymmetric unit contains only one title molecule (Fig. 1).
The distances between the cyclopentadienyl ring centroids and the Fe atom are 1.644 Å and 1.634 Å, respectively. The cyclopentadienyl rings of the ferrocenyl group are parallel with a dihedral angle of 1.9 (3)° between the corresponding least-squares planes. These metrical parameters are typical of the η5···Fe···η5 coordination of the ferrocenyl moiety. The O1—C11—C12—C13—N1 skeleton is coplanar (rms deviation = 0.005 Å). The C≐O, C≐C and C≐N bond lengths are intermediate between their corresponding double and single bonds indicating that the π-system is partially delocalized in the framework. Likewise, the skeleton is nearly coplanar with the C5H4 ring with an angle of 6.9 (2)° between the mean planes. On the other hand, the angle between the least-squares planes of O1—C11—C12—C13—N1 and the bromophenyl ring C16/C20 is 33.8 (1)° out of the plane showing the lack of conjugation between both systems.
The molecular structure of the enaminone-containing compound is also stabilized by an intramolecular N-H···O hydrogen bond between the amine and the carbonyl groups (Table 1). This feature has been previously described by Fuentealba et al. (2008).
