(Received 28 October 2013; accepted 6 November 2013; online 9 November 2013)

In the title compound, [Co₄(C₅H₅)₄(μ₃-CCH₂SiMe₃)(μ₃-H)], the Co atoms form a distorted tetrahedron with the ethylidyne moiety bridging three of the Co atoms as well as the hydrido ligand also bridging three of the Co atoms. The Co—Co bond lengths in the Co₄ tetrahedron vary from 2.3844 (4) to 2.4608 (4) Å. Each Co atom is additionally η⁵-bonded to a cyclopentadienyl (Cp) anion.

Comment top

The reaction of the [CpCo] precursor CpCo(hexadiene) with the titanocene alkyne complex Cp*₂Ti(η²-Ph₂PC₂PPh₂) was investigated to synthesize a new heterobimetallic complex. However, only the degradation of the [CpCo] precursor complex was observed. The title compound consists of a tetrahedral Co₄ core. Two Co atoms (Co1 and Co2) feature a hexa-coordination by one Cp ligand, three Co atoms and the bridging hydrido- and ethylidyne unit. The other two Co atoms (Co3 and Co4) feature a penta-coordination mode. While the Co3 atom is surrounded by the Cp unit, three Co atoms and the hydrido ligand, the Co4 atom is coordinated by its Cp ligand, also three Co atoms and the ethylidyne unit. The Co—Co distances vary from 2.3844 (4) Å (Co3—Co4) to 2.4608 (4) Å (Co1—Co2). The vector C1-C2 is almost perpendicular to the Co1, Co2, Co4 plane and the Co—C distances are similar to those obtained for a Co₄ cluster described by Wadepohl et al. (1993). The µ₃-bridging hydride was found in a difference Fourier map and Co—H distances of about 1.65 Å were found (Co1—H1 1.67 (3), Co2—H1 1.64 (3), Co3—H1 1.65 (3) Å).

Experimental top

To a stirred solution of Cp*₂Ti(η²-Ph₂PC₂PPh₂) (180 mg, 0.253 mmol) in 10 ml of THF was added a solution of crude CpCo(hexadiene) (0.81 M, 3.12 ml) (contaminated with a small amount of CpCo(H₂C=CHSiMe₃)₂) in THF. The reaction mixture was stirred for 16 h at 45°C and then cooled to room temperature. After removing all the volatiles in vacuum, the dark brown residue was dissolved in 6 ml of a mixture of THF/n-hexane (1:2). Dark brown crystals of the title compound, suitable for X-ray analysis were grown after 14 days at -78 °C, being a degradation product of the small impurities mentioned above. Noteworthy, the µ₃-(trimethylsilyl)ethylidyne unit results from this starting material CpCo(H₂C=CHSiMe₃)₂.

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.
