The crystal structure of dimeric -oxalato-bis[(6-p-cymene)(triphenylphosphine)ruthenium(II)] bis(tetrafluoroborate), [Ru2(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(6-p-cymene) bonds in the complex lying trans to the phosphine group. The related mononuclear species (6-p-cymene)(oxalato)(pyridine-3,5-dicarboxylic acid)ruthenium(II), [Ru(C2O4)(C10H14)(C7H5NO4)], crystallizes as hydrogen-bonded tapes linked through O-HO hydrogen bonds.
