(Received 25 June 2010; accepted 3 July 2010; online 14 July 2010)

In the title triangulo-triruthenium(0) compound, [Ru₃(C₂₅H₂₂As₂)(C₆H₁₂Cl₃O₃P)(CO)₉], the bis(diphenylarsino)methane ligand bridges an Ru—Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru₃ triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. In the crystal packing, the molecules are linked by intermolecular C—H⋯O hydrogen bonds into a three-dimensional framework. Weak intermolecular C—H⋯π interactions further stabilize the crystal structure.

Comment top

Triangulo-triruthenium clusters are known for their interesting structural variations and related catalytic activity. A large number of substituted derivatives, Ru₃(CO)_12-nL_n (L= group 15 ligand) have been reported (Bruce, et al., 1988a,b; Bruce et al., 1985). As part of our study of the substitution of transition metal-carbonyl clusters with mixed-ligand complexes, we have published several structures of triangulo-triruthenium-carbonyl clusters containing mixed P/As and P/Sb ligands (Shawkataly et al., 1998, 2004, 2010). Herein we report the synthesis and structure of the title compound.

The bond lengths and angles of title compound (Fig. 1) are comparable to those found in a related structure (Shawkataly et al., 2010). The bis(diphenylarsino)methane ligand bridges the Ru1—Ru2 bond and the monodentate phosphine ligand bonds to the Ru3 atom. Both the phosphine and arsine ligands are equatorial with respect to the Ru₃ triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings (C1–C6/C7–C12 and C14–C19/C20–C25) are 85.4 (5) and 87.3 (5)° for the two diphenylarsino groups respectively.

In the crystal packing (Fig. 2), the molecules are linked by intermolecular C19—H19A···O6, C27—H27B···O9 and C30—H30A···O5 hydrogen bonds into a three-dimensional framework. Weak intermolecular C—H···π interactions further stabilize the crystal structure (Table 1).

Experimental top

All manipulations were performed under a dry, oxygen-free dinitrogen atmosphere using standard Schlenk techniques. All solvents were dried over sodium and distilled from sodium benzophenone ketyl under nitrogen. Tris(2-chloroethyl)phosphite (Aldrich) was used as received and µ-bis(diphenylarsino)methanedecacarbonyltriruthenium(0) (Bruce et al., 1983) was prepared by a reported procedure. The title compound was obtained by refluxing equimolar quantities of Ru₃(CO)₁₀(µ-Ph₂AsCH₂AsPh₂) and tris(2-chloroethyl)phosphite in hexane under nitrogen atmosphere. Crystals suitable for X-ray diffraction were grown by slow solvent / solvent diffusion of CH₃OH into CH₂Cl₂.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
