The title compound, [Ru2(C22H34Si2)(CO)4], contains two RuI atoms linked by a bridging (η5-tBuC5H2)2(SiMe2)2 ligand (tBu is a tert-butyl and Me is a methyl group) with an Ru—Ru bond length of 2.8401 (7) Å. The dihedral angle between the planes of the cyclopentadienyl rings of the ligand is 123.13 (19)°. The four terminal carbonyl ligands are bound in a symmetrical and staggered array. In the crystal, molecules are linked via pairs of C—H⋯O hydrogen bonds, forming inversion dimers.

A solution of (C5H3tBu)(SiMe2))2 (80 mg, 0.22 mmol) and Ru3(CO)12 (80 mg, 0.13 mmol) in xylene (20 ml) was refluxed for 15 h. After removal of the solvent under reduced pressure, the residue, which was dissolved in a minimum amount of CH2Cl2, the solution was chromatographed on an alumina column using petroleum ether–CH2Cl2 (5:1) as
A yellow band was eluted and collected. After removal of the solvents under vacuum from the above the residue was recrystallized from n-hexane/CH2Cl2 (1:1) at 263 K to give colourless crystals of the title compound (54 mg, 36%). Anal.

Experimental. Spectroscopic data for the title compound: 1H NMR (CDCl3): δ 5.26 (s, 4H, C5H2), 1.33 (s, 18H, C(CH3)3), 0.44 (s, 6H, Si(CH3)), 0.23 (s, 6H, Si(CH3)). IR (νCO): 2016(s), 1964(s), 1953(s), 1918(s) cm-1. |
Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
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. |

Recently, a series of reactions of doubly-bridged ligand precursors (C5H4(E))(C5H4(E')) (E, E' = CH2, CMe2, SiMe2, or GeMe2) with Ru3(CO)12 have been reported by the group of Professor Angelici (Ovchinnikov et al., 2002) and our groups (Zhu et al., 2012), which generally afforded the corresponding doubly-bridged bis(cyclopentadienyl) dinuclear complex containing an elongated Ru—Ru bond. To develop a deeper understanding of the relationship between the structure of the ligand and the Ru—Ru bond distance, and make a comparison of the Ru—Ru bond distance with those in the respective non-bridged and singly-bridged bis(cyclopentadienyl) ruthenium analogues, we carried out the reaction of the doubly-bridged ligand precursor (tBuC5H3)2(SiMe2)2 with Ru3(CO)12 in refluxing xylene, which afforded the expected title product whose crystal structure we report on herein.
The molecular structure of title compound is presented in Fig. 1. It has approximate C2v symmetry, as reflected in the small torsion angle DCp(centroid)–Ru1–Ru2–Cp(centroid) (ca. 15.8°). The dihedral angle between the planes of the Cp rings of the (η5-C5H2tBu)2(SiMe2)2 ligand is rather large, 123.13 (19) °, which results in a longer than normal Ru1–Ru2 single bond distance of 2.8401 (7) Å, longer than that [2.8180 (3) Å] in its parent complex [(η5-C5H3)2(SiMe2)2]Ru2(CO)4 (Ovchinnikov et al., 2002). Therefore, the two tBu substituents on title compound have considerable effect on the geometry of the system.
The elongated Ru—Ru distance makes CO bridging unfavorable. This situation is similar to that in other doubly-bridged analogues, for example 2.8420 (8) Å in [(η5-C5H3)2(CMe2)(SiMe2)]Ru2(CO)4, 2.824 (1) Å in [(η5-C5H3)2(CMe2)(GeMe2)]Ru2(CO)4, 2.8382 (9) Å in [(η5-C5H3)2(CH2)(SiMe2)]Ru2(CO)4, 2.8429 (7) Å in [(η5-C5H3)2(CH2)(GeMe2)]Ru2(CO)4 (Zhu et al., 2012), and 2.821 (1) Å in the fulvalene diruthenium carbonyl complex (η5:η5-C10H8)Ru2(CO)4 (Boese et al., 1997).
Generally, due to the rigid structure of the doubly-bridged ligand, the Ru—Ru bond distances in the above-mentioned complexes are obviously longer than those in the respective non-bridged and singly-bridged analogues, for example 2.735 (2) Å in trans-[(η5-C5H5)Ru(CO)(µ-CO)]2 (Mills et al., 1967), 2.7879 (4) Å in (CMe2)[(η5-C5H4)Ru(CO)2]2 (Burger, 2001), or 2.705 Å in (SiMe2)[(η5-C5H4)Ru(CO)(µ-CO)]2 (Zhou et al., 1997; Bitterwolf et al., 1996).
