Abstract

The crystal structure of dimeric mu-oxalato-bis[(eta(6)-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(eta(6)-p- cymene) bonds in the complex lying trans to the phosphine group. The related mononuclear species (eta(6)-p-cymene)(oxalato)(pyridine-3,5-dicarboxylic acid)ruthenium(II), [Ru-(C2O4)(C10H14)(C7H5NO4)], crystallizes as hydrogen-bonded tapes linked through O-H center dot center dot center dot O hydrogen bonds.
