Abstract top

The crystal structure of the title compound, [Ru(C12H12O6)(C18H15P)2(CO)], confirms its formulation as a ruthenabenzofuran, with a slightly distorted octahedral coordination environment at the RuII ion, and mutually trans triphenylphosphine ligands. The metallabicyclic ring system is essentially planar (maximum deviation 0.059 Å).

Comment top

Metallabenzenes are now a well established class of organometallic compounds and a considerable number of studies involving the syntheses, reactivity, aromatic character and decomposition pathways of these materials have been made (Bleeke, 2001, Landorf & Haley, 2006, Wright, 2006). In contrast, studies of fused ring metallabenzenoids such as metallanaphthalenes (Paneque et al., 2003) and metallabenzofurans (Clark et al., 2006) are much more rare. We recently reported that protonation of a carbon atom in the five-membered ruthenafuran ring of the known ruthenabenzofuran, Ru[C5H2(CO2Me-2)(CO2Me-4)(CHCO2Me-5)](CO)(PPh3)2 (2) (see Fig. 2) (Yamazaki & Aoki, 1976, Bruce et al., 2000) provides a new route to ruthenabenzenes (Clark et al., 2009). While following the literature synthesis of this ruthenabenzofuran, (Yamazaki & Aoki, 1976), we were able to isolate through chromatography a small amount of a previously unreported, isomeric ruthenabenzofuran, Ru[C5H2(CO2Me-1)(CO2Me-4)(CHCO2Me-5)](CO)(PPh3)2 (1) (see Fig. 2). We now report details of the structure of (1) (Fig. 1) which confirms its formulation as a ruthenabenzofuran, with essentially octahedral coordination at Ru, and mutually trans triphenylphosphine ligands. The metallabicyclic ring system is essentially planar. The C—C bond lengths within the six-membered ring show a small but significant alternation, similar to that reported in the isomeric ruthenabenzofuran (Bruce et al., 2000) in which one of the methyl ester substituents resides on C2 rather than C1. This change has no important impact on the structural parameters of the metallabicyclic ring system. The bond length alternations in these two ruthenabenzofuran isomers are more pronounced than in the tethered ruthenabenzene derived from the isomer reported by Bruce (Bruce et al., 2000) by protonation at C6 (Clark et al., 2009).

Experimental top

RuH2(CO)(PPh3)3 (1.00 g, 1.09 mmol) and methyl propiolate (0.55 g, 0.58 ml, 6.54 mmol) were heated under reflux in benzene (50 ml) for one hour. The initially pale yellow-green solution changed to red-brown soon after the solution reached boiling point. The solvent was removed under vacuum and the residue purified by chromatography on silica gel using dichloromethane/ethanol (98:2) as eluent. Two coloured bands were eluted from the column. The first band, which was coloured blue, was collected and on evaporation of the solvent dark blue crystals of the title compound were obtained (0.0098 g, 1%). The second, much larger red-purple band contained the related ruthenabenzofuran, Ru[C5H2(CO2Me-2)(CO2Me-4)(CHCO2Me-5)](CO)(PPh3)2 (2), previously reported in the literature (Yamazaki & Aoki, 1976). The crystal of Ru[C5H2(CO2Me-1)(CO2Me-4)(CHCO2Me-5)](CO) (PPh3)2 (1) that was used for the single-crystal X-ray diffraction study was grown from dichloromethane/ethanol solution.

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.
