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

S. Huh and A. J. Lough

Abstract: In the title compound, [FeRu(C₁₇H₁₄P)₂(C₆H₈BN₄)H(CO)]·C₃H₆O, 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 [H₂Bpz₂]^- ligand (pz = pyrazolyl) is 85.67 (7)°. The latter ligand creates an RuN₄B 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-HO hydrogen bonds between complex molecules and acetone solvent molecules.
