Abstract top

In the title triangulo-triruthenium compound, [Ru3(C25H22As2)(C18H15Sb)(CO)9], the bis(diphenylarsino)methane ligand bridges an Ru-Ru bond and the monodentate stibine ligand bonds to the third Ru atom. Both the stibine 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 three stibine-substituted phenyl rings make dihedral angles of 84.3 (3), 80.4 (3) and 70.5 (3)° with each other. The dihedral angles between the two phenyl rings are 85.9 (3) and 75.2 (3)° for the two diphenylarsine groups. In the crystal packing, molecules are linked into chains down the c axis via intermolecular C-H...O hydrogen bonds. Weak intermolecular C-H...[pi] 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-nLn (L= group 15 ligand) have been reported (Bruce et al., 1985, 1988a,b). As part of our study on 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, 2009). Herein we report the synthesis and structure of Ru3(C18H15Sb)(C25H22As2)(CO)9.

The bond lengths and angles of title compound (Fig. 1) are comparable to those found in a related structure (Shawkataly et al., 2009). The bis(diphenylarsino)methane ligand bridges the Ru1—Ru2 bond and the monodentate stibine ligand bonds to the Ru3 atom. Both the stibine 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 three stibine substituted phenyl rings make dihedral angles (C26–C31/C32–C37, C26–C31/C38–C43 and C32–C37/C38–C43) of 84.3 (3), 80.4 (3) and 70.5 (3)° with each other respectively. The dihedral angles between the two phenyl rings (C1–C6/C7–C12 and C14–C19/C20–C25) are 85.9 (3) and 75.2 (3)° for the two diphenylarsino groups respectively.

In the crystal packing (Fig. 2), the molecules are linked together into chains via intermolecular C13—H13B···O8 along c axis. 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. Triphenylstibine (Fluka) used as received and µ-bis(diphenylarsino)methanedecacarbonyltriruthenium(0) (Bruce et al., 1983) was prepared by reported procedure. The title compound was obtained by refluxing equimolar quantities of Ru3(CO)10(µ-Ph2AsCH2AsPh2) (105.5 mg, 0.1 mmol) and triphenylstibine (35.3 mg, 0.1 mmol) in hexane under nitrogen atmosphere. Crystals suitable for X-ray diffraction were grown by slow solvent / solvent diffusion of CH3OH into CH2Cl2.

Refinement top

All hydrogen atoms were positioned geometrically and refined using a riding model with C—H = 0.93–0.97 Å and Uiso(H) = 1.2 Ueq(C). The final difference Fourier map reveals high peaks, ~1.5 e Å-3, two of which are quite separate from the heavy atoms. These could be due to the presence of additional solvent, possibly methanol, and perhaps at partial occupancy. Attempts to produce a satisfactory model of this solvent were not successful.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems 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.
