Comment top

Ferrocene compounds are of great interest in the field of material chemistry (Togni & Hayashi, 1994). In this paper we reported the synthesis and crystal structure of the title compound. The molecular structure of the compound consists of a methylphenylsilyl unit and two ferrocene units. In the ferrocene unit, the cyclopentaienyl rings linked to the same Fe atom are approximately eclipsed and the interplanar angles are 1.76 (24) and 3.35 (21)°, respectively. The Fe atom is slightly closer to the substituted cyclopentadienyl ring. The distances of the Fe1 atom from the centroids of the unsubstituted and substituted cyclopentadienyl (Cp) rings is 1.648 (1) and 1.645 (1) Å, respectively. The distances of the Fe2 atom from the centroids of the unsubstituted and substituted Cp rings is 1.653 (2) and 1.650 (2) Å, respectively.

Experimental top

Ferrocene (2.00 g, 26.88 mmol) was dissolved in 12 ml of anhydrous tetrahydrofuran (THF). In the course of 15 min a solution of 10.8 mmol t-BuLi (7.16 ml of a 1.5 M n-Pentance solution) was added dropwise at 0°C. n-Hexane (16 ml) was then added, and the solution was kept at -78°C for 15 min, before the orange precipitate was filtered off. The precipitate was washed with small portions of n-hexane. The FcLi was dissolved in THF (15 ml) and added to a solution of dichloromethylphenylsilane (0.8 g, 4.69 mmol) in n-hexane (20 ml) at 0°C, and then stirred overnight at room temperature. The precipitate was filtered and the solvent was evaporated under vacuum. the orange residue was purified by recrystallization from n-hexane to give 4.04 g of orange product in 88% yield.

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.
