Abstract top

The title compound, [Fe2(C5H5)2(C21H21N3O2)], a potential novel N,N',N''-tridentate ligand with (non-crystallographic) C2 axial symmetry, adopts a U-shaped molecular conformation.

Comment top

Ferrocene derivatives have come a long way as a tool in chemistry, with applications in electrochemistry, materials science, synthesis and catalysis (Feng et al., 2008). The resurgence of interest in 1,2-disubstituted planar-chiral ferrocenes has resulted in numerous interesting compounds which are finding widespread application in asymmetric catalysis (Richards & Locke, 1998; Kagan & Riant, 1997). Our past success in the use of chiral C2-symmetric bisferrocenyl aminophosphine ligands in asymmetric catalysis (Song et al., 1999; Cho et al., 1999) has prompted us to examine related bisferrocenyl analogues, such as the title complex (I), as potential sources of chiral ligand. The α-diimine ligands are now well known to stablize organometallic complexes (van Koten & Vrieze, 1982) and have thus been widely employed in a number of catalytic reactions (Fache et al., 2000). Herein, an example of a completely new class of C2-symmetric bisferrocenyl amides, (I), that was formed via the reaction of 2,6-bis(chlorocarbonyl)pyridine with two equivalents of ferrocenyl ethylamine, is described.

The structure of (I), Fig. 1, shows the conformation of the nearly parallel Cp rings [the dihedral angle between their planes are 2.32 (1) and 1.04 (1)° for Fe1 and Fe2, respectively] is almost eclipsed in one ferrocene unit, whereas staggered by 5(2)° in the other. The two amide groups are nearly coplanar with the pyridine ring. The dihedral angles between the plane of the substituted Cp rings and central pyridyl ring are 86.6 (2) and 42.2 (2)°, respectively.

Experimental top

To a mixture of 2,6-bis(chlorocarbonyl)pyridine (244.0 mg, 1.21 mmol) and triethylamine (1.0 ml) in CH2Cl2 (10.0 ml) was added a solution of ferrocenyl ethylamine (0.43 g, 2.42 mmol) in CH2Cl2 (20.0 ml). The mixture was stirred at room temperature for 8 h after which it was washed with 5% HCl (3 x 20 ml) and 5% NaHCO3 (4 x 30 ml). The product was separated by extraction with CH2Cl2, dried over magnesium sulfate, and the solvent removed. The remaining oily residue was eluted on a silica gel column with a mixture of CH2Cl2 and MeOH (95:5). The first orange band was collected, and the solvent evaporated to give an orange solid (750 mg, 65.2% yield). Single crystals were grown by slow diffusion of hexane into a CH2Cl2 solution of (I).

Refinement top

H atoms were positioned geometrically (C—H = 0.93–0.98 Å and N—H = 0.86 Å), and refined as riding with Uiso(H) = 1.2Ueq(C,N).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
