[1,1′-Bis(diphenyl­phosphino)ferrocene]carbon­yl[dihydro­bis(pyrazol-1-yl)borato]hydridoruthenium(II) acetone solvate

In the title compound, [FeRu(C(17)H(14)P)(2)(C(6)H(8)BN(4))H(CO)]·C(3)H(6)O, the Ru(II) ion is coordinated in a distorted octa­hedral environment involving a hydride ligand, a carbonyl ligand and two bidentate ligands. Of the two bidentate ligands, the bulky 1,1′-bis­(diphenyl­phosphino)ferrocene (dppf) ligand chelates with a larger bite angle of 101.90 (2)°, whereas the bite angle of the [H(2)Bpz(2)](−) ligand (pz = pyrazol­yl) is 85.67 (7)°. The latter ligand creates an RuN(4)B six-membered ring with a boat conformation, which puckers towards the site of the small hydride ligand. The hydride ligand is cis with respect to the carbonyl ligand and trans to one of the P atoms of the dppf ligand. In the crystal structure, there are weak inter­molecular C—H⋯O hydrogen bonds between complex mol­ecules and acetone solvent mol­ecules.
