μ-Bis(di-o-tolyl­phosphan­yl)methane-1:2κ2 P:P′nona­carbonyl-1κ3 C2κ3 C3κ3 C-diphen­yl(phenyl­sulfanylmeth­yl)phosphane-3κP-triangulo-triruthenium(0) dichloro­methane 0.25-solvate

摘要

In the title compound, [Ru3(C29H30P2)(C19H17PS)(CO)9]·0.25CH2Cl2, the atoms of the dichloro­methane solvent mol­ecule have a fractional site occupancy of 0.25; the dichloro­methane mol­ecule is disordered about an inversion centre. The bis­(di-o-tolyl­phosphan­yl)methane ligand bridges an Ru—Ru bond and the monodentate phosphane ligand bonds to the third Ru atom; its S-bonded phenyl ring is disordered over two orientations in a 0.53 (4):0.47 (4) ratio. All the P atoms are equatorial with respect to the Ru3 triangle: each Ru atom also bears one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings attached to each P atom of the diphenyl­phosphanyl ligand are 68.4 (2) and 71.5 (2)°. In the crystal, mol­ecules are linked into [001] chains via inter­molecular C—H⋯O hydrogen bonds. Weak inter­molecular C—H⋯π inter­actions also occur.
