(Received 4 October 2012; accepted 2 November 2012; online 10 November 2012)

The structure of the title compound, [Fe(C5H5)(C10H12N2)]I, consists of a 1-(ferrocen-1-ylmeth­yl)-3-methyl­imidazolium cation which is counter-balanced by an iodide anion. The cyclo­penta­dienyl (Cp) rings of the ferrocene unit have a slightly staggered conformation skewed from an ideal eclipsed conformation by an angle of 3.5 (6)°. The inter­planar angle between the Cp and the imidazole ring is 67.94 (2)°.

Comment top

The versatility of ferrocene has seen it be derivatized into a variety of compounds. Because of its stability and unique electronic and redox properties, ferrocene and its derivatives have been successfully applied with much success in various fields including medicinal chemistry (Ornelas, 2011, Simenel et al., 2003). Ferrocenyl imidazolium salts are a special class of ferrocene derivatives which have a cationic ferrocene-imidazole moiety [FcIm+] balanced by an inorganic anion X-. These compounds can be applied as ionic liquids (Taylor & Licence, 2012; Gao et al., 2004) and as precursors to ferrocenated imidazolium carbenes (Coleman et al., 2005). The title compound was synthesized via solvent-free conditions providing an economical and clean product requiring less tidious purification process similar to reactions by Bala and Coville (2007) in which one of the reagents is a liquid and acts as a solvating medium.

The average bond lengths between the iron atom (Fe1) and the centroids of the substituted Cp ring (C6–C10) and the unsubstituted Cp ring (C1–C5) are 2.0382 (6) and 2.0354(7.4). The cyclopentadienyl rings of the ferrocene moiety have a slightly staggered conformation. The staggering angle between the two rings is 3.5 (6)° which is smaller than that of Nyamori & Bala (2008), Nyamori et al., (2010) and Nyamori et al., (2012)

Experimental top

In a round bottom flask, methyl iodide (1.64 ml, 3.75 g, 26.4 mmol) was added to 1-Ferrocenylmethyl-1H-imidazole (2.00 g, 7.50 mmol) and allowed to reflux for 12 hrs, at 50 °C under innert atmosphere. The reaction mixture was then allowed to cool to room temperature and washed with anhydrous diethylether (3 x 10 ml). A yellow solid was obtained, which was further dried invacuo. Yellow crystals crystals were obtained from recrystallization in diethylether (2.78 g, 91%); m.p. 134–136 °C (lit. 130–135 °C); IR (ATR cm-1) 3430, 3042, 1567, 1549, 1429, 1150, 1040, 837, 820, 755, 620, 500, 482; 1H NMR (CDCl3) 10.13 (1H, s, NCH), 7.16 (2H, m, NCH), 5.38 (1H, q, CH), 4.43 (2H, t, C5H4), 4.32 (2H, t, C5H4), 4.29 (5H, s, C5H5), 4.06 (3H, s, NCH3); 13C NMR (CDCl3) 136.12, 123.63, 121.91, 78.83, 70.09, 69.46, 50.12, 37.15; m/z (ESI) [M+] - I 281.

Carbon-bound H-atoms were placed in calculated positions [C—H = 0.98 Å for Me H atoms, 0.99 Å for Methylene H atoms, 0.99–1.00 for methine H atoms and 0.95 Å for aromatic H atoms; Uiso(H) = 1.2Ueq(C) (1.5 for Me groups)] and were included in the refinement in the riding model approximation.

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.
