Oxalate complexes of the (η6-p-cymene)ruthenium(II) fragment: μ-oxalato-κ2O1,O2: κ2O1′,O2′- bis[(η6-p-cymene)(triphenylphosphine-κP)-ruthenium(II)] bis(tetrafluoroborate) and (η-p-cymene)

The crystal structure of dimeric μ-oxalato-bis[(η6-p- cymene)(triphenylphosphine)ruthenium(II)] bis(tetrafluoroborate), [Ru 2(C2O4)(C10H14) 2(C18H15P)2](BF4) 2, has the cation lying on an inversion centre. The complex demonstrates the trans bond-weakening influence, with the longest Ru-C(η6-p-cymene) bonds in the complex lying trans to the phosphine group. The related mononuclear species (η6-p-cymene) (oxalato)(pyridine-3,5-dicarboxylic acid)ruthenium(II), [Ru(C2O 4)(C10H14)(C7H5NO 4)], crystallizes as hydrogen-bonded tapes linked through O-H⋯O hydrogen bonds. © 2006 International Union of Crystallography.
