Abstract:
In the title compound, (eta(6)-p-cymene)[(diphenylphosphinofluorido)trifluoroborato-kappa(2)P,F][(diphenylphosphinoylfluorido)trifluoroborato-kappaO]ruthenium(II), [Ru(C(12)H(10)BF(4)OP)(C(12)H(10)BF(4)P)(C(10)H(14))], the hybrid Ph(2)PFBF(3) ligand is bidentate (kappa(2)P,F) and thus forms a five-membered chelate ring. The Ph(2)PFBF(3) ligand is unusually ligated to the metal through the P atom of the PPh(2) moiety and through one of the F atoms of the BF(4) moiety. The phosphine-oxidized Ph(2)P(O)FBF(3) ligand is bonded to the Ru atom via the O atom. The Ru centre has a pseudo-octahedral coordination environment, in which the phenyl ring occupies three of the corners of the distorted octahedron. The Ru-O, Ru-F and Ru-P bond lengths are 2.107 (3), 2.135 (4) and 2.3145 (15) A, respectively.
