1,4-Diferrocenylbutane-1,4-dione

Abstract

In the crystal structure of the title compound, [Fe2(C5H5)2(C14H12O2)], each carbonyl group is coplanar with the adjacent cyclo­penta­dienyl ring, thus maximizing the π-orbital overlap and electronic inter­actions between the groups. In the crystal structure, there are inter- and intra­molecular C—H(...)O contacts.

Comment

Since its first discovery in 1951 (Kealy & Pauson, 1951), particular attention has been paid to ferrocene and its derivatives owing to their unique structural, spectroscopic and electrochemical properties. In recent years, a number of extensive studies has been conducted on ferrocene containing compounds and polymers, and particularly compounds exhibiting multiple ferrocene groups with the opportunity for producing mixed-valent states due to their potential use in chemical and biochemical sensors (Navarro et al., 2005; Brown et al., 2005; Okochi et al., 2005; Hickman et al., 1991), as redox active catalysts (Togni & Hayashi, 1995; Sawamura & Ito, 1992; Nicolosi et al., 1994), because of their application in molecular magnets (Miller et al., 1988), and for use in self-assembled monolayer chemistry (Chidsey et al., 1990; Creager & Rowe, 1997). Such monolayers containing covalently connected ferrocene groups have been reported to be prepared in mixed-valent, fully oxidized or fully reduced states (Pugh et al., 2006). Hence, in order to increase their potential for the aforementioned applications, the chemical properties of the monolayers can be controlled via application of the appropriate voltage. Due to the electron transfer of ferrocene being generally chemically and electrochemically reversible and occurring via an outer-sphere redox mechanism, ferrocene derivatives are not only perfect candidates to be incorporated into technological devices, but also ideal molecules for the study of interfacial electron and charge transfer. We report here the single-crystal structure of the title compound (I).

The molecular structure of (I), is shown in Fig. 1. Succinylferrocene crystallizes in the orthorhombic space group Pca21 with one molecule in the asymmetric unit. The ferrocene groups themselves are in the eclipsed conformation and the bond lengths and angles associated with the ferrocene groups are as expected. Two ferrocenyl groups are almost trans to each other. The average values of the C—Cg1—Cg2—C and C—Cg3—Cg4—C (Cg1, Cg2, Cg3 and Cg4 are the centroids of the C1—C5, C6—C10, C15—C19 and C20—C24 rings, respectively) pseuodo-torsion angles are 5.50 (2)° and 7.13 (2)° respectively. The Fe1–Cg1, Fe1–Cg2, Fe2–Cg3 and Fe2–Cg4 distances are 1.635 (2) Å, 1.649 (2) Å, 1.645 (3)Å and 1.647 (2) Å, respectively, with Cg1–Fe1–Cg2 and Cg3–Fe2–Cg4 angles of 179.54 (10)° and 178.65 (11)°. Within the molecule, the carbonyl substituents are almost coplanar with the plane of the adjacent Cp rings (r.m.s. deviations = 0.0278 (2) Å and 0.0559 (2) Å; Cp versus. C=O dihedral angles: 7.42 (6)° and 13.74 (5)° respectively), therefore maximizing the π-orbital overlap and electronic interactions between the groups. In (I), the intermolecular bond lengths and angles are unexceptional; the central C—C distance, 1.492 (6) Å, is close to the value found in 1,6-diferrocenylhexane-1,6-dione, 1.506 (5) Å (Pugh et al., 2006). The space between the ferrocene units is nearly close packed and the ferrocene moieties are closer to each other in the solid state (7.903 (21) Å which is the distance between Fe1 and Fe2) than they would be on average in solution.

In the crystal structure, weak inter and intramolecular C—H···O hydrogen bonding interactions link molecules (Table 1, Fig. 2) and may be effective in the stabilization of the structure.

Experimental

The title compound (I) was prepared by employing Alkyl Lewis acid, EtAlCl2 (Gemici, 2005). To a CH2Cl2 solution (10 ml) containing ferrocene (1.27 g, 6.8 mmol), EtAlCl2 (6.8 ml; 1.0 M in hexane) was added dropwise at 273 K under nitrogen. The resulting mixture was stirred at 273 K for 1,5 h. The solution was then extracted with portions of CH2Cl2 (3 times; in total 75 ml), dried over Na2SO4 and evaporated to dryness. Final purification was achieved by flash chromatography on silica gel utilizing CHCl3 as the eluant. The product was obtained in 76% yield. 1H-NMR (400 MHz, CHCl3, δ, p.p.m.): 3.05 (broad m, 4H, COCH2CH2CO), 4.20 (s, 10H, 2xC5H5), 4.40 (broad s, 4H, C5H4), 4.76 (broad s, 4H, C5H4). X-ray quality single crystals of (I) were prepared via solvent evaporation from hexane/ethyl acetate solutions to give reddish platelets.

Refinement

The H atoms were all located in a difference map, but they were repositioned geometrically. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H = 0.93 and 0.97 Å) and Uiso(H) = 1.2 times Ueq of the parent atom, after which the positions were refined with riding constraints.

Special details

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.
